Diego Garcia Military Base and British Indian Ocean Territory Bill

Priti Patel Excerpts

2nd reading
Tuesday 9th September 2025 Commons Chamber

[Priti Patel (Witham) (Con)]

I beg to move an amendment, to leave out from “That” to the end of the question and add:

“this House declines to give a Second Reading to the Diego Garcia Military Base and British Indian Ocean Territory Bill because it implacably opposes the United Kingdom ceding sovereignty over the British Indian Ocean Territory to Mauritius, and is therefore opposed to the terms of the Treaty to which the Bill gives effect, in particular Article 11 of the Treaty which will mean the United Kingdom paying £34.7 billion to Mauritius, leading to tax rises in the United Kingdom to provide tax cuts in Mauritius; because the Treaty does not secure the base on Diego Garcia, in particular because it does not embody the “right to extend” the 99-year lease to which the then Secretary of State for Foreign, Commonwealth and Development Affairs referred in this House on 7 October 2024; because the measures in the Treaty leave the base vulnerable, and therefore represent a threat to the strategic interests of the United Kingdom; and because the Treaty does not properly protect the rights of the Chagossian people, or the future of the Marine Protected Area.”

We on the Opposition side of the House stand against Labour’s £35 billion Chagos surrender deal. Everything about this surrender deal is wrong, from the way it was negotiated behind closed doors within weeks of Labour coming to power, to the betrayal—[Interruption.] I will happily give way.

[Graeme Downie]

The right hon. Lady says “behind closed doors”. Will she please publish the previous Government’s negotiating position, including the cost of the deal they were looking to do?

[Priti Patel]

Let me be clear: I was not a member of the previous Government, but the hon. Member knows perfectly well that no one on the Conservative Benches has any authority to publish classified papers from previous Governments. [Interruption.] He might laugh about that, but those on the Labour Benches might want to apologise to Lord Cameron of Chipping Norton, who actually stopped the deal. He has been grossly misrepresented this afternoon in this debate.

[Graeme Downie]

[Mr Calvin Bailey]

[Priti Patel]

I will return to that point in a minute.

On top of what else is wrong with this surrender deal, it is a fundamental betrayal of the British Chagossian community, whose rights have been ignored and neglected. I pay tribute to them. They have joined us today in the Gallery. If I remember rightly, this is the fifth or sixth time they have joined us to show how strongly they feel about the deal.

The deal undermines the defence and security interests of this country, and it brings a risk of the destruction of the unique marine environment and a failure to protect the future of the marine protected area. From refusing to grant this House a meaningful debate and vote on the treaty when it came, to the scenes in the Mauritius National Assembly—I hope Labour MPs watched the debates in the Assembly, where the Prime Minister was gloating about how easy it was to secure concession after concession from the Labour Government—and the deceit, misinformation and gaslighting of the British people through to the £35 billion cost to hard-working British taxpayers, which will be used to fund tax cuts in Mauritius.

[Richard Tice]

I am most grateful to the shadow Foreign Secretary for giving way. The Minister described the deal as an investment. Does the right hon. Lady agree that it would be helpful to educate him that a freehold is an investment and a lease is a liability?

[Priti Patel]

Exactly right. On top of that, there is the whole issue of the liabilities, costs and everything else that goes with it. The hon. Gentleman makes a fundamental, important point.

[Sarah Bool (South Northamptonshire) (Con)]

We talk about the cost. The TaxPayers’ Alliance has concerns about the amounts we are calculating, because they will be dependent on inflation. The calculations do not take into account market values, so the £35 billion stated by the Government Actuary’s Department will actually be more like £47 billion.

[Priti Patel]

Absolutely right. Of course, this Government do not like speaking about inflation for all the macro-economic reasons we know about. Inflation under this Government continues to rise, which speaks volumes about their handling of the economy.

This deal is so bad for Britain, it has left our country humiliated and weaker on the world stage. Our friends and enemies alike are laughing at the UK and Labour’s epic diplomatic failure to stand up for our national interests.

[Alex Ballinger]

The right hon. Lady says that this is an international problem for the UK, but does she not agree that the Americans, the Canadians, the New Zealanders, the Australians, the Indians and even the Pope support the deal? It is really important that our Five Eyes security partners are behind us.

[Priti Patel]

Having led Five Eyes for our country—I am very proud to have done so—it is a matter of great concern that the deal has been backed by Iran, China and Russia. I say to the hon. Gentleman that that is exactly why this is a bad deal for our country. [Interruption.] It is correct, actually, and I can point him to the references where those countries have spoken in favour of the deal.

[Peter Swallow (Bracknell) (Lab)]

I thank the right hon. Lady for giving way. I am going to give her another opportunity to confirm that she agrees with our Five Eyes allies that this is a good deal. Those are the people who back this deal.

[Priti Patel]

I met our Five Eyes partners at the weekend and I can tell the hon. Gentleman that they are not paying for this deal and they are not gloating about it. They see it very much as a failure of this Government. He can go and justify that to his constituents.

I congratulate the Minister on his new post and his promotion, and I welcome him to this wider discussion. He has tried his best to sell the surrender deal to the House, but the choices made by his Prime Minister, the former Foreign Secretary who is no longer in post, the Attorney General and Labour Ministers will leave Britain weaker and poorer, humiliated into giving away the sovereignty of our British territory and paying a fortune, £35 billion, to lease back a base—the point has been made a number of times—that we already own. While Labour has spent months trying to hide the details of its Chagos surrender deal and the scale of the financial cover up, it has been the Conservatives holding Labour to account constantly, exposing its shameful decision.

[Mr Calvin Bailey]

I come back to the right hon. Lady’s point about security. I must have misread our colleagues in the US Department of Defence when they told Defence Committee members, some of whom are sat behind her and heard the same words, that they did not understand her consternation about the deal—but let us assume that she has not put that in an incorrect way. If there was not a problem, will she please explain why her party started the negotiations?

[Priti Patel]

For the benefit of the House and everyone, to provide absolute clarity again, it was the Conservative Foreign Secretary who ended all discussions on this matter. I say it again: in all respect to Lord Cameron—[Interruption.]

[Several hon. Members rose—]

[Priti Patel]

No, sit down. In all respect to Lord Cameron, I think the Labour party should apologise for the gross misrepresentation that has taken place. Speaking of Foreign Secretaries, it is a real shame that the new Foreign Secretary is not here today to speak on the Bill. She could have come in, reviewed the details and got out the slide rule, which would be quite a good tool in this case. [Interruption.] I have just heard that the treaty has been signed, without it even coming to this House for debate and a vote. The Foreign Secretary could have come to the House to review the deal—she could even have scrapped it and saved the British taxpayer billions of pounds. However, like her predecessor, she has left it to junior Ministers to defend the deal.

[Several hon. Members rose—]

[Priti Patel]

I will give way once again to the hon. Member for Halesowen (Alex Ballinger).

[Alex Ballinger]

Could the right hon. Lady outline what was in the deal that the last Conservative Foreign Secretary was negotiating? The points of sovereignty and everything else were conceded by her party.

[Priti Patel]

I will now give way to the hon. Member for Kilmarnock and Loudoun (Lillian Jones).

[Lillian Jones (Kilmarnock and Loudoun) (Lab)]

Could the right hon. Lady tell me why the US and the Five Eyes have backed this deal?

[Priti Patel]

They have not gone on the record to say that they have. I have already made it quite clear why it is not in our interest.

It tells us something about Labour’s priorities that within days of coming into office, the Prime Minister met the then Prime Minister of Mauritius to commit to the surrender deal. Encouraged by the Prime Minister’s obsession with left-wing activism and distorted views of international law, and advised by one of the Prime Minister’s best friends and supporters—one could even say his cheerleader—Mauritius knew it was on to a winner negotiating with this naive, foolish and Britain-hating Labour Government. True to form, instead of standing up for Britain’s interests, Labour rushed to accept the advisory opinion of a foreign court that few had heard of, and swiftly agreed to Britain’s surrender of sovereignty.

[Dr Caroline Johnson]

Is my right hon. Friend aware of any of our allies who think that the insecure and expensive leasehold deal that we have now is better than the freehold sovereignty and security that we had before?

--- Later in debate ---

[Priti Patel]

My hon. Friend makes a good point. I have not heard our Five Eyes allies speak about it being a good way of effectively securing any national interest whatsoever—the concept of leasehold is completely wrong.

[Dr Murrison]

The Government are clearly not going to take any lessons from us, but I wonder whether they would listen to one of their own. Lord West of Spithead was a Security Minister under the previous Labour Administration and then First Sea Lord and Chief of the Naval Staff, so he knows a thing or two. He has said very clearly that in his expert opinion, this deal is “irresponsible” and that it will damage our strategic interests. Who are we to believe: the Labour party or my old boss, Lord West?

[Priti Patel]

My right hon. Friend is absolutely right.

There is something fundamental here about the negotiations—I think the Minister alluded to this earlier on. The Government were effectively just listening to leftie lawyers and advisory judgments and acting because they were frightened that their left-wing lawyer friends would pursue even more lawfare against us. The Minister of State, Foreign, Commonwealth and Development Office, the hon. Member for Cardiff South and Penarth (Stephen Doughty) told the Foreign Affairs Committee:

“Our view is that, without this deal, it was inevitable that Mauritius would pursue and secure a legally binding judgment against the UK. Indeed, legally binding provisional measures could also have been secured within weeks”.

The Government have never—not once—detailed what the legal threat is beyond hiding behind spurious aspects of international law.

I have to say that it is a defeatist attitude that Labour has taken. Britain is Europe’s leading defence power, a pillar of NATO in Europe and a P5 member of the UN Security Council with a right of veto. We are not bound by advisory judgments pursued by Mauritius at the ICJ—which, by the way, included a judge who is a member of the Chinese Communist party. By being vocal in conceding defeat and unwilling to defend Britain from a barrage of lawfare, Labour has let Britain’s standing on the world stage plummet, and its decisions will have serious consequences for us.

Let us talk about the money. We all know that this Labour Government are big spenders when it comes to splashing about taxpayers’ money, and the costs of Labour’s surrender treaty are astronomical at £34.7 billion—a figure which, by the way, we had to drag out of the Government Actuary’s Department because Labour Ministers repeatedly refused to disclose the cash payments when asked. In fact, because the payments are linked to inflation, as my hon. Friend the Member for South Northamptonshire (Sarah Bool) has pointed out, guess what? The cash cost could be even higher. That means higher taxes for our constituents, which is nothing for those on the Labour Benches to crow about.

[Peter Swallow]

The right hon. Lady comes to this Chamber claiming that this deal has astronomical costs and all that, but what she will not put on the record is the cost of the deal that the Conservatives were negotiating. She can say all she wants about that being a matter for the public record, but she needs to be clear with the British public.

--- Later in debate ---

[Priti Patel]

I will be absolutely crystal clear for the benefit of this House and for Hansard, too: there was no deal whatsoever. The Government can put out as much fake news as they wish and carry on pretending and crowing that there was a deal, but there was no deal. It was the last Conservative Foreign Secretary who stopped any negotiations and discussions, and they were stopped—Lord Cameron himself has said that. On that basis alone, I think Labour Members should all apologise to Lord Cameron, and perhaps even correct the record.

[Sir Bernard Jenkin (Harwich and North Essex) (Con)]

I am most grateful to my right hon. Friend for giving way. Does it not speak volumes about the real nature of this Government that despite facing a fiscal crisis and potentially a crisis in their finances—they want more money spent on health and benefits, because that is what they do—their priority is listening to leftie lawyers pontificating about decolonisation and committing billions of pounds of long-term liabilities to give away and lease back something that we already own? Does that not say something about the extraordinarily myopic preoccupations of this Government? Of course, we told the Foreign Office to get lost.

[Priti Patel]

My hon. Friend is absolutely right. It speaks volumes about the priorities that this Labour Government—socialist to the core in how they like to spend public money—are focused on. Come November, when the Chancellor has her Budget, there will be no point crowing about the past and blaming other people, other countries and international forces and factors. This is a fiscal mess made by this Labour Government with this utterly scandalous, appalling and reckless financial giveaway.

[Dr Luke Evans]

The Minister challenged the Opposition and the shadow Chancellor about our position on net present value, but the reason is that the use of NPV is unprecedented. It is used for commercial deals that the Government make and is standardised for that alone, not for international agreements on sovereignty. Does my right hon. Friend agree that we will not change on net present value, which has its place in commercial deals but not in giving away sovereignty?

[Priti Patel]

My hon. Friend is absolutely right; it is absolutely shameful. I come back to the fundamental principle that this House will have to consider: at a time when hard-pressed British taxpayers are struggling, with significant tax rises and the share of the tax burden on the public going up, the Government will have to have a good, hard look at themselves and justify this appalling cost to their own constituents.

[Joy Morrissey (Beaconsfield) (Con)]

My right hon. Friend made an excellent point earlier about the underlying socialism in this agreement. The initial agreement—[Laughter.] No, let me just clarify: the initial agreement from May very clearly says it is about apologising for the colonisation of Mauritius and that it is about the regrettable legacy. Everything is laid out: it is about apologising for our British history and heritage. It is not about being proud of protecting our sovereignty, protecting the realm and protecting our security. We should not be saying that we will apologise and pay out because we feel bad about everything that we have done. That is the difference between the Conservatives and the Labour party, and that is why we are taking such objection to this Bill.

[Priti Patel]

I thank my hon. Friend for that intervention. I say gently to some Labour Members, who are laughing and sneering at a fellow Member of this House when she is making a very valid point, that they are simply being disrespectful. It says a great deal. The hon. Member for Dunfermline and Dollar (Graeme Downie) can laugh as much as he wants. The British public see Labour as a party that does not stand up for Britain and British values, and that is not something to be laughed or sneered at.

[Sir Iain Duncan Smith]

I am grateful to my right hon. Friend. Just to settle this whole argument about net present value, the reason it simply cannot be used for a long-term treaty obligation is that it is necessary to make a really heavy estimation of what will happen socially and economically in that area. It is just about possible to use some of that in the UK, where the Government control certain aspects, which they will not control after this treaty is signed. That is why it has been recommended that it not be used for long-term effects when not within the UK. That is why the actuarial department advised going for the total amount, not this net present value.

[Priti Patel]

My right hon. Friend is absolutely correct.

[Paul Holmes]

My right hon. Friend is concerned about the cost of the deal, but does she also share my concern about the way in which the deal was negotiated? The Prime Minister of Mauritius has said that only the Prime Ministers of our respective countries were in the room; officials were asked to leave the room, so there are no records of what was discussed. Is that how a responsible, democratic Government should show transparency when negotiating on the international stage?

[Priti Patel]

My hon. Friend is absolutely right; at the heart of this is transparency about negotiations, including fiscal negotiations.

[Graeme Downie]

The right hon. Lady talks about transparency, but once again we have not heard a word from her about what her Government’s position would have been, so there has been no transparency at all. They went through 11 rounds of negotiations. If she did not believe a deal was possible, surely she would have stopped after two or three. She knew that a deal was vital to UK security interests, but her Government could not conclude it.

[Priti Patel]

The hon. Member, who was laughing and sneering at fellow colleagues earlier—that is simply not acceptable—should have listened to what I said. I will restate it for the House: there was no deal done whatsoever.

[Alex Ballinger]

Will the right hon. Member give way?

[Priti Patel]

I will not. As we have already heard from Conservative Members, we have rarely seen the methodology that the Government are now hiding behind used for any spending announcements. When the Minister winds up, I wonder if he will commit to presenting all future spending decisions using this methodology—or perhaps he could explain why the Government have singled out this large and embarrassing expenditure to be formulated in this way. That is down to the fact that they are covering up a colossal cost.

[Sir Roger Gale]

The point has been made over and over in this discussion that we are giving away something that we did not have to give away, and are renting it back—and the British taxpayer is paying for it. Last week, I asked the Leader of the House how much this was going to cost. She said,

“alongside legislation we publish all the necessary documents, including the costings, which we have been transparent about.”—[Official Report, 4 September 2025; Vol. 772, c. 453.]

I regard the Minister as a friend, but to say the least, his figures have been opaque. Let me ask one simple question that my right hon. Friend might know the answer to: how much is the United States contributing to this deal?

[Priti Patel]

I thank my right hon. Friend for his contribution, and for pursuing this line of question in the Chamber with other Ministers. He is absolutely correct. We know that the United States of America is not contributing to the cost of the deal. The cost is solely on the British taxpayer. [Interruption.] Operational costs of the base are different; that is not in this treaty or this Bill.

The Bill represents a series of measures, not the treaty in its entirety. The Government blocked this House from voting on the treaty during the 21-day process provided for in the Constitutional Reform and Government Act 2010. Last week, when asked at oral questions why we were not getting a vote on the costs, the then Foreign Secretary—now Deputy Prime Minister—proclaimed that there would be a vote, but the Government have not seen fit to put forward a motion. As the explanatory notes to the Bill confirm, the Bill will not authorise expenditure. That is not acceptable. We will table amendments to the Bill to hold the Deputy Prime Minister to his word and ensure that this House has a rightful say over the payments to Mauritius.

Let us be clear: unless there is a direct vote on the costs, Labour will have cheated Parliament and Britain out of having a say on the financial implications of the £35 billion that British taxpayers are being forced to pay a foreign Government. That expenditure means higher taxes for British taxpayers and less spending for British people across all constituencies around the country. Shamefully, this is all to fund tax cuts, debt reduction and new investment in not our country, but Mauritius. I will gladly give way to any Minister or Government Back Bencher who wants to explain why it is acceptable to deny Parliament a vote on this £35 billion of expenditure, and why the money should be given to a foreign Government, not invested in this country. If they need to check that with Rachel from accounts or Lord Hermer, I am sure they can do so before the end of the debate. Labour giving away British taxpayers’ money to a foreign Government to rent land that we already own is reckless and irresponsible.

[Dr Caroline Johnson]

My right hon. Friend is making a great speech. She says that this is a reckless giving away of British money. Unlike many of the other things we have had to watch Labour do, such as take the winter fuel allowance away from old people and heavily tax charities, hospices and others, this cannot be undone. Once the money is given away to a foreign country, there is nothing that any future Government can do to claim it back easily.

[Priti Patel]

My hon. Friend is right. At the end of the day, the real judge of this will be the British people.

[Phil Brickell]

Will the right hon. Member give way?

[Priti Patel]

No, I am answering my hon. Friend. The real judge will be the British people. How will they view a Labour Government giving away £35 billion to a foreign Government? That money could be spent in this country. It is simply not acceptable at all.

[Peter Swallow]

Will the right hon. Member give way?

[Priti Patel]

I am going to make progress, and I have taken plenty of interventions.

The Minister touched on the base at Diego Garcia, which is one of the most important military assets in the world. It gives us and our US allies significant global reach, but the treaty undermines that position, and the Bill contains no measures to mitigate its effects.

[Alex Ballinger]

Will the right hon. Member give way?

[Priti Patel]

I will not; I have given way plenty of times to the hon. Gentleman.

The surrender of sovereignty means that Britian will be a rule taker, taking the laws, rules and commands of Mauritius, and that restricts and impedes base operations. For example, Mauritius has signed up to the Pelindaba treaty, banning the stationing and storage of nuclear weapons; no Minister has been able to provide a definitive answer when questioned about how that may impact our security and defence, once the UK is no longer sovereign in, or able to exercise sovereign rights over, the Chagos islands and Diego Garcia.

Under the terms of the treaty, we are bound to notify Mauritius of various activities relating to our use of the base, including operations from the base against that country, and movements of our allies’ vessels. Despite heavy questioning, at no point have Ministers explained in detail how the notifications will work, and who will have access to the information.

[Jim Allister (North Antrim) (TUV)]

The shadow Foreign Secretary is coming to the nub of the matter. This is about the future security of the world, including the United Kingdom. We are arriving at a situation where the sovereign power is a signatory to an empty nuclear treaty that prohibits the stationing of nuclear weapons anywhere within the ambit of the countries that are signatory to that treaty. How could we even use this base for our nuclear submarines?

[Priti Patel]

The hon. and learned Member is absolutely right. That is why it was important to have a debate on the Floor of the House when the treaty came together, but we did not have one. The treaty brings into question everything about security, including our ability to be as strong and secure as we need to be.

It will come as no surprise to Members to hear that now that our sovereignty over the base is being surrendered, our enemies are queuing up to—guess what?—make friends with Mauritius. Just days before the surrender treaty was signed, Russia agreed a new partnership agreement with Mauritius that includes marine research. That so-called “marine research” conducted by Russia could take place just a handful of miles away from our base. Mauritius has also been courted extensively by Iran and China for further partnerships in a range of other areas. Despite the warnings, this inept Labour Government have failed to act to safeguard our interests.

[Alex Ballinger]

Will the right hon. Member give way?

[Priti Patel]

No, I have given way to the hon. Gentleman many times.

[Sir Bernard Jenkin]

rose—

[Priti Patel]

I will give way one more time to my hon. Friend.

[Sir Bernard Jenkin]

On the previous question of how much operational independence we will really have, can my right hon. Friend comment on point 4 of annex 1 of the agreement, entitled “Mauritian Security Review”, which requires us to consult Mauritius before any

“construction or emplacement of any maritime installation”

or

“any proposal for development in the land territory of the Chagos archipelago”?

It also states that Mauritius shall conduct a security review, and that our permission to carry out works is dependent on the outcome of the Mauritius security review. We do not have operational independence under this treaty. It then goes through the dispute process, and there is no decisive way of deciding anything unless there is agreement between the two Prime Ministers. It is a completely inadequate agreement.

[Priti Patel]

My hon. Friend has summed it up: the whole process is completely inadequate, with no transparency and no dispute resolution mechanisms. This is just too messy, given that we are talking about the defence and security of the country. Again, this is exactly why we should have been able to debate the treaty on the Floor of the House and give it the scrutiny that is required. Let us hope that the Prime Minister and his lefty lawyers are not involved in the dispute resolution mechanisms, because Britain will come out worst. As we know, when Labour negotiates, Britain loses.

At the press conference announcing the signing of the treaty, it was interesting to hear the Prime Minister almost gaslighting critics of the treaty by comparing them—that is, us—to China, Russia and Iran as he arrogantly declared his views and position. On 4 and 11 June in the House, he said that the treaty “has been opposed by our adversaries, Russia, China and Iran”. We know that 6,000 miles away, at the celebration party press conference in Mauritius, China was singled out by the Mauritian Government for praise. According to the press release, Deputy Prime Minister Paul Bérenger noted that China’s

“unwavering support played a critical role in the international recognition of Mauritian sovereignty.”

A few days later, the Chinese ambassador issued Mauritius with “massive congratulations” on securing the surrender of the Chagos islands. This summer, the Mauritian Government published a press release saying that the President expressed “gratitude” for China’s “unwavering support” for Mauritius’s sovereignty claim over the Chagos archipelago.

Iran has also been supportive of the Mauritian claim for the Chagos islands, with its ambassador saying earlier this year:

“The Islamic Republic of Iran has always supported Mauritius’s position regarding the Chagos issue. So, Chagos belongs to the Mauritian people. We support its return and have made many efforts in the past toward that goal.”

As for Russia, when meeting Putin, the former Mauritian President Vyapoory stated:

“We appreciate the support of Russia in our claim for our sovereignty on Chagos.”

Ministers have been asked in parliamentary questions for the evidential basis of the Prime Minister’s claims about the apparent opposition of those three countries who threaten our interests, but they have not come forward with it. When the Minister responds, will he finally explain the grounds behind the Prime Minister’s malicious, almost spurious, remarks, or apologise for those claims? All the evidence shows that, far from opposing the surrender treaty, our enemies actually back it, which means that Britain is weaker.

[Mr Calvin Bailey]

Will the right hon. Member give way?

[Priti Patel]

I will not. I know that the hon. Gentleman will speak later.

I turn to the British Chagossians. As well as undermining our security and defence interests and ripping off British taxpayers, Labour has betrayed the British Chagossians. Members on both sides of the House have recognised and acknowledged that the Chagossian community has faced injustice and hardship. Their removal from the Chagos islands is a source of great and profound regret. I pay tribute to the Chagossian community in Britain for their campaigning, and to Henry Smith, our former colleague as Member of Parliament for Crawley, who kept pursuing and raising the issue, and who fought in the House for their rights. As a result, we gave the community new rights in the Nationality and Borders Act 2022, which Labour voted against. I hope that the Minister can give assurances that those rights will not be undermined by the citizenship measures in clause 4 of the Bill. Because of that past, it is so important that any decisions made about the future of the Chagos islands are made with the community in mind, and that their needs are fully respected.

Ten years ago, when the Minister of State, Foreign, Commonwealth and Development Office, the hon. Member for Cardiff South and Penarth (Stephen Doughty), was the Opposition’s spokesman, he said:

“The people of Chagos must be at the heart of decisions about their future…the UK Government have a fundamental moral responsibility towards the islanders that will not go away.”—[Official Report, 28 October 2015; Vol. 601, c. 192WH.]

But this treaty fails them. I have met the community many times and heard their concerns and frustrations; I think everyone in the House will acknowledge their frustrations. They feel that they have been ignored throughout the process, and that the treaty has no guarantees for them. There is a £40 million Chagossian trust fund that UK taxpayers will capitalise, but the UK and the British Chagossians will have no control or say over how it will be used or controlled by the Government of Mauritius. I highlight that point because the Chagossians feel strongly—they fundamentally know—that they cannot trust the Government of Mauritius. The Bill and the treaty make no provision for the British Chagossians to benefit from the trust fund, or be involved in its governance; nor are they guaranteed any right to visit the Chagos islands. Those decisions will be controlled by Mauritius once sovereignty is surrendered.

Hon. Members across the House who have spoken up for British Chagossians know of their fears. It is right that I amplify those fears, or at least raise them in the House, because their voices have not been heard. Now is the time for them to be counted, for their voices to be heard, and, importantly, for their rights to be defended.

Another damning indictment of the Bill and the treaty is the way in which they fail to safeguard the 640,000 sq km marine protected area. Its unique biodiversity enables important marine research to be conducted. In just the last few weeks, a study that included researchers from Exeter and Heriot-Watt universities and the Zoological Society of London was published. It noted:

“Our results provide clear evidence for the value of the Chagos Archipelago VLMPA for protecting a diverse range of large and mobile marine species.”

Yet all we have heard thus far from the Government is warm words about intentions to continue with an MPA. No details have been published.

[Dr Luke Evans]

On the conservation point, is it not that the case has already been tested in UNCLOS between 2010 and 2015, when it was said that we could not go ahead with a marine protection area for this British territory because we had not consulted properly with Mauritius? At that point, it was also determined that UNCLOS could not rule on sovereignty as that was not its basis. So we found out not only about the sovereignty side, but that we cannot protect the islands on the environmental part. What guarantees does my right hon. Friend see in the treaty that we will have ecological protections in the area, given those findings?

[Priti Patel]

My hon. Friend is absolutely correct about UNCLOS and in highlighting the insecurities and serious challenges. It may be forthcoming, but at this stage we do not know what levels of protection will be provided or will continue. We do not know what level of resource Mauritius will put into the MPA or what the UK will contribute.

[Dr Murrison]

My right hon. Friend is making a powerful case. The answer is none, because Mauritius has no navy and practically no coastguard. With which means will Mauritius defend a territory that is hundreds of kilometres away? It cannot possibly do so.

[Priti Patel]

My right hon. Friend has summed it up, and it is not just that Mauritius is unable to do so; it clearly will not be interested in this whole area.

It is important for the House to reflect on that point. After decades of investment in and support for the MPA, there is now a major issue of jeopardy. We do not know at this stage what the governance arrangements will be. In fact, in response to questions about that from my hon. Friend the Member for Bognor Regis and Littlehampton (Alison Griffiths) at the Environmental Audit Committee in April, the Minister, Baroness Chapman, said:

“It will belong to the Government of Mauritius, and they will make decisions about how they protect the seas around the Chagos archipelago… You want more detail than we have… We and the Government of Mauritius want to see the marine protected area continue, but I do not know what the precise nature of it will be.”

What we do know is that the Fisheries Minister of Mauritius, Dr Boolell, is eyeing up the marine protected area to exploit it. He boasted to his National Assembly on 7 February that he wants to issue fishing and trawler licences. He declared that

“what stops me tomorrow to say that I am going to give fishing licence for any fishing trawler company or any fishing vessel to go to any part of Chagos”.

This issue has been raised extensively in the Foreign Affairs Committee, with no Minister being able to give any assurances. If the Bill passes and the treaty is implemented, the unique marine environment will be put at risk.

I will briefly touch on two areas. Another part of the Chagos surrender Bill that should concern the House is its Henry VIII clause. Clause 5 grants the Government a free hand, with little or no parliamentary scrutiny, decisions or authority, to

“make any provision that appears to his Majesty to be appropriate as a result of the Treaty”.

That could mean the Government making further concessions to the Government of Mauritius. With the treaty making provision for a joint commission with the UK and Mauritius, that could take place without anyone in this House having any sight or knowledge of it. We need a clear commitment from the Minister in his winding-up speech what those measures will be or will he rule out on the Floor of the House that any further concessions will be made to the Government of Mauritius?

In conclusion, this Bill, its six shameful clauses and the treaty it partly implements are a damning indictment of the failures of this Labour Government. It surrenders sovereignty of a land we own to a foreign Government, increasingly allied and growing closer to countries that are not our allies and which pose the biggest threats to our national security and defence. It binds the hands of British taxpayers into paying £35 billion—a surrender tax. It puts the interests and demands of a foreign country and left-wing lawyers above our national interests. It leaves our country poorer, weaker and less able to defend our interests from foreign threats and it undermines our standing in the world.

Labour’s Chagos surrender deal is an epic failure of diplomacy and an expensive humiliation for Britain. When Labour negotiates, Britain loses. His Majesty’s loyal Opposition will continue to stand up for Britain’s national interests and our defence and security. We will fight for our sovereignty, we will defend British taxpayers by opposing Labour’s surrender tax and, we will make the case for the British Chagossians to have their rights safeguarded and the marine protected area preserved. We will oppose this Bill and fight this treaty every step of the way.
