Diego Garcia Military Base and British Indian Ocean Territory Bill

Graeme Downie Excerpts

2nd reading
Tuesday 9th September 2025 Commons Chamber

[Luke Pollard]

My hon. Friend is exactly right. On the reasoned amendments, my colleague who is to conclude the debate, the Minister of State, Foreign, Commonwealth and Development Office, my hon. Friend the Member for Cardiff South and Penarth, will respond to some of the details of the reasoned amendment selected by Mr Speaker. However, there is a lot of misinformation about this treaty, and I believe that in some cases it is deliberate misinformation to confuse the picture. Clearly, securing the operation of the base is the priority of this Government and of this treaty. Indeed, I believe in good faith that it was the priority of the previous Government as well, which is why they started the negotiations and held them for 11 rounds, and why we concluded them, because we agreed with the previous Government that securing the future operation of the base was the priority. That is why they started them; that is why we completed them.

[Graeme Downie (Dunfermline and Dollar) (Lab)]

The Minister has already outlined the support of the British overseas territories. Will he please remind us of who else supports the Bill? Who supports it and who else opposes it, in addition to the Conservative party?

[Luke Pollard]

I will come to the level of international support in a moment, but our allies back this Bill and support it strongly. When we look at which column people choose to be in—the column of those in support of the Bill, with our allies, with India, the United States and others, or the column of countries and people who oppose it—I know which side I am on. I am on the side of our allies. It is up to each of the opposition parties to choose whether they oppose the Bill and to decide which column they are in. That is a choice not for me, but for them. Only one column has our allies in, including our principal security partner, the United States. It is on the side of the treaty.

[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.

[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.

--- Later in debate ---

[Graeme Downie (Dunfermline and Dollar) (Lab)]

We have heard from Members on the Opposition Benches a slew of political opportunism, scaremongering, some cliché bingo and some derogatory terms—something that belongs more in a tabloid than in this House—about the Chancellor of the Exchequer.

Back when these negotiations started, the Conservative party knew that a deal was needed—it may have been somewhere on its list of priorities when it still had some lingering credibility about the good of the nation. The Conservative party knew that a deal was in the best interests of the United Kingdom and our allies. It knew that without a deal, Mauritius could very well have pursued a sovereignty claim and allowed Russia and China into the waters around Diego Garcia. People do not sit through 11 rounds of negotiations if they do not think something is important; they walk away. To give the previous Government credit, they did not do that. They understood the importance of a deal.

[Dr Evans]

On that basis, there were 17 rounds of formal negotiations for the Falkland Islands between ’65 and ’82. What would the outcome be under the hon. Gentleman’s way forward?

[Graeme Downie]

That point was covered before. We have already seen scaremongering from the Opposition about the other British overseas territories, including the Falkland Islands and Gibraltar. I hope that the Conservative party will reflect on and apologise for that.

None the less, the previous Government knew that a deal would keep Britain safe. They knew that without a deal, international courts could effectively make the base inoperable, and they knew that that could plant China right on our doorstep. Now, they cannot even say why it was important. They cannot say why they even started the negotiations; several Government Members have raised that point, and not once have the Conservatives been able to say why, other than hiding behind the fact that they are being entirely politically opportunist. They knew all that, and they now pretend that none of it matters. They are playing politics with Britain’s safety.

[Cameron Thomas (Tewkesbury) (LD)]

It is rare that I find myself aligned with the Conservative party, but I share its concerns for the structure and veracity of this deal. That being said, does the hon. Member share my bewilderment that the Conservative party has chosen this particular hill to die on, given that the Bill is as much a product of its work as it is of Labour’s?

[Graeme Downie]

I thank the hon. Member for his intervention. At the beginning of the intervention, I was going to point out that there were five years during which the Liberal Democrats were very close to the Conservative party, but I will remove that thought from my head and agree with him. This does seem a very strange hill for the Conservative party to die on, but I am not surprised by the level of hypocrisy we have seen from some Conservative Members.

That is the real hypocrisy. The Conservatives have attacked the cost of this deal, but they will not reveal what their own deal would have cost. Government convention means that their numbers are locked away—secret, hidden, unable to be scrutinised and compared. They will hide and hide. Would Conservative Front Benchers like to give any figure, in any currency of their choosing? What was their number? How much was it going to cost? What was the number on the bottom of the piece of paper after 11 rounds of negotiations? The truth is that this Government secured the deal that the Conservative party knew was critical for our national security, but could not deliver.

While we are talking about costs, let us put this into perspective. As the Minister said in his opening speech, France pays €85 million a year for a base in Djibouti, one that shares a fence with a Chinese naval facility and enjoys none of the security that comes with this Government’s deal on Diego Garcia. Diego Garcia is 15 times bigger, more secure, and delivers unmatched operational freedom for the United Kingdom and our allies. Let us be clear about what this treaty delivers. It secures Diego Garcia; it locks in control of the land, the sea and the electromagnetic spectrum; and it shuts out foreign militaries from the outer islands. That is a serious deal—a deal that represents value, one that the Tories could never close, but now choose to attack from behind a shield of secrecy.

[Lincoln Jopp]

I do not know whether the hon. Member listened to the outstanding, forensic dismantling of the Government’s case by my right hon. and learned Friend the Member for Kenilworth and Southam (Sir Jeremy Wright), but on the basis that every constituency in this country will kiss away the opportunity to have £52 million as a result of this deal—that is what it is going to cost in total—would he like to tell the people of Dunfermline and Dollar why he would rather give away that amount of money to a foreign Government on a spurious legal basis than invest it in his own constituency?

[Graeme Downie]

I thank the hon. Member for his intervention—he is someone for whom I have a lot of respect. I would tell my constituents that this country is now safer and more secure because of the deal that this Government have done.

Let us see who is on the Government’s side. The United States backs the deal, with President Trump having called it

“a very long-term, powerful lease”.

Australia, Canada, New Zealand, India, NATO and the overseas territories all back the deal, because they understand that Diego Garcia is vital to our security and theirs. Who lines up against it? Who is the proud company that the Conservatives keep? Nigel Farage and Reform.

[Madam Deputy Speaker (Caroline Nokes)]

Order. We do not refer to Members by name, but by constituency.

[Graeme Downie]

I apologise for that, Madam Deputy Speaker.

We have seen Reform UK peddling fantasies about America that were flatly wrong. Beyond these shores, what do we see? Vladimir Putin and Xi Jinping in Beijing both know that they could have access to the waters around Diego Garcia were it not for the deal that this Government have secured. That is the roll-call—that is who Conservative Members stand with, and that is who they will be voting alongside if they block the Bill. We saw Reform swaggering around, claiming that it would get President Trump to block this deal, but the truth has been the exact opposite. The United States has clearly welcomed this treaty, as we have heard so often this afternoon. Reform did not just misread the room; it misread and misrepresented one of our closest allies, talking Britain down and peddling fantasy while a serious Government deliver and secure our safety. This Bill is about strength and weakness. This is strength and that is weakness—order from the Government versus chaos from the Opposition, Britain standing with our allies versus Britain opening the door to our adversaries.

Just a couple of years ago, the Conservatives knew that this deal was vital. They wanted it in office—like the hon. Member for Tewkesbury (Cameron Thomas), it pains me to sometimes agree with the Conservatives, but for once, they were correct. They were right to want this deal, but only when they lost power did they suddenly discover their doubts. That is not principle; it is opportunism.

[Sir Jeremy Wright]

I understand the argument that the hon. Gentleman is making, but why does he think that the last Government did not make the deal?

[Graeme Downie]

I thank the right hon. and learned Gentleman for his intervention. I listened very carefully to his speech—it was very interesting indeed, and I respect his viewpoint. My short answer is that the last Government just could not seal a deal, like they could not seal a deal with the EU and could not seal a trade deal with India. They abandoned the people of this country.

I will close by saying that I will proudly vote for this Bill tonight. It puts the UK on the side of our allies and on the side of security, and ensures that we will be protected for generations to come.

--- Later in debate ---

[Paul Holmes]

If the hon. Gentleman had bothered to show up for the entire debate—I think that he has only just arrived in the Chamber—then he would have heard the answer to those questions in excellent speeches given by hon. Members from across the House. In response to his question, why is the deal also backed by so many counties that have malign influences towards the interests of the United Kingdom, such as Russia, China and Iran? If he stays for the rest of the debate, he might hear some answers to those questions too. It is easy for Labour Members to stand in the Chamber and read a Labour party briefing, thinking that if they say things time and again, they must be true, and that people outside the Chamber will expect what they say will be true.

I was the Parliamentary Private Secretary to Lord Cameron of Chipping Norton when he was Foreign Secretary. He said to Foreign Office officials at that time that the negotiations that had started and were being explored went past his red line. My right hon. Friend the Member for Braintree (Sir James Cleverly), who was Foreign Secretary when some of the negotiations happened, said to his Foreign Office officials, “As the democratically elected Foreign Secretary, these recommendations go beyond my red lines.” Those negotiations were then stopped by Lord Cameron—I remember him instructing Foreign Office officials to stop those negotiations—so I say to hon. Members, including the hon. Member for Dunfermline and Dollar (Graeme Downie), that just because negotiations and conversations have started, we do not have to accept a conclusion that we do not want.

[Graeme Downie]

As we have heard already in the debate, apparently we cannot hear a negotiating position, so will the hon. Gentleman describe in detail exactly what those red lines were?

[Paul Holmes]

I will tell the hon. Gentleman what one of those red lines was: not paying £35 billion to another country. In case he wants to read his Labour party briefing again, I remind the hon. Gentleman that another red line for the last Foreign Secretary was that he clearly did not accept unilaterally that the sovereignty of the Chagos islands fell with Mauritius. That is a key difference between the last Government and this Government.

This is a bad deal for Britain: it will cost £35 billion, while the Government tax and spend and make people in this country poorer, and in an ever-changing international security situation, this country is unilaterally giving up a strategically important defence base, in an area of the world where we are seeing more geopolitical uncertainty. I cannot put into words how bad this Bill is, except to say that it is an act of self-sabotage that we have not seen in this House by a democratically elected Government for generations.

To reiterate, not only is this a bad deal, but it is backed by every nation that is malign to our national interest, including China, Russia and Iran. Last week, at an international summit, those countries were actively advocating some of the malign influences about which this Government and the last Government spoke about, and they are actively backing this deal. I challenge Labour Members to look Opposition Members or any of their constituents in the eye and say that a deal that is successful for this country should be backed by Iran, China and Russia.

Madam Deputy Speaker, I am trying to work within the confines of parliamentary etiquette, but I have to say that there is something deeply concerning about the way that this Government have chosen to negotiate the terms of the agreement. We have to look at the close links between the key people who negotiated this deal with the Mauritian Government and the links—private links—to the Prime Minister and Ministers in this Government. The Prime Minister of Mauritius has said in the Mauritian Parliament that officials were asked to leave the room while private negotiations were going ahead. I have never known a responsible Government who are trying to hand over sovereignty of a British overseas territory to ask officials, who are there to protect the integrity and the transparency of the of decisions that Ministers take, to leave the room so that a negotiation can go on. Why have the Government hidden the cost of the deal? Why have they refused to give this House a solid and sustainable way to scrutinise the decisions of the Government? They have avoided scrutiny at every turn.

Diego Garcia Military Base and British Indian Ocean Territory Bill

Graeme Downie Excerpts

Committee of the whole House
Monday 20th October 2025 Commons Chamber

[Wendy Morton]

I think the hon. Gentleman needs a little memory check, because we did not propose a deal.

The British Chagossians, some of whom are watching from the Gallery—I pay tribute to them for their dignified and strong campaigning over many, many years—have been betrayed by Labour. Their rights have been ignored, as have their fears, leading to hundreds fleeing Mauritius and coming here. Labour’s surrender Bill, as presented, does nothing for them. It does nothing for the marine protected area—one of the most important and largest marine environments in the world—which has been protected while under British sovereignty and has become a centre for scientific research and development. That is at risk, and promises and aspirations announced by Ministers to ensure that it continues are not reflected in the Bill.

Shockingly, Labour’s surrender Bill as drafted does nothing to safeguard, defend and protect our national security. Labour is surrendering British sovereignty and territory to a country that is increasingly aligned with China.

[Graeme Downie (Dunfermline and Dollar) (Lab)]

The right hon. Lady describes this as a surrender Bill. Can she please tell me which flag will be flying over the Chagos islands if this is a so-called British surrender? It will be a British flag that is flying. Is that a point she understands?

[Wendy Morton]

There will be one flag that is flying, and that is the white flag of surrender.

Thousands of Mauritian public officials are being trained—or should that be “indoctrinated”?—by China on courses the Chinese are paying for. Both Russia and China are signing partnerships with Mauritius, but Labour’s surrender Bill fails to protect our interests.

--- Later in debate ---

[Wendy Morton]

It can be very easy to back something when you do not have to pay for it, but let us move on.

Now, the Government are failing to take seriously the warnings about China, and the threats it poses to Diego Garcia and our military assets and interests in the Indo-Pacific. Labour’s surrender Bill is bad for British taxpayers, bad for our national security, bad for the marine environment and bad for the Chagossians. It also grants Ministers huge powers to make further decisions and avoid parliamentary scrutiny.

Amendment 1 would in effect block Labour’s surrender treaty coming into force and the dissolution of the British Indian Ocean Territory unless and until Ministers reveal the legal advice they have received about Britain’s ability to extend and exercise sovereign rights over Diego Garcia after the initial 99-year period. The Government constantly claim they have secured the military base, but they have totally failed to do that. All they have done is pay Mauritius £35 billion to lease back a base we currently own, but only for 99 years. We have no certainty whatsoever about the fate of the base after the 99-year period. After paying Mauritius £35 billion, it would kindly give us the option to extend the treaty for another 40 years, but on what terms? If we extend it, will Mauritius make it conditional on more extortionate payments? What if we are outbid by a hostile power? In fact, what is to stop China putting in a bid? If no agreement is reached before the specified deadline and the base is offered to another country, what will happen to all the fixed assets belonging to Britain? We have had no answers from the Government on any of these vital points, which is unacceptable, and the terms of the treaty and the Bill, as they stand, are reckless.

Amendment 7 is necessary because the Government’s legal justification for surrendering the Chagos islands constantly shifts, because it has no legal basis. As my right hon. and learned Friend the Member for Kenilworth and Southam (Sir Jeremy Wright) explained on Second Reading, the Government’s entire legal case is spurious. Many of us have been asking where the binding judgment we are constantly told is inevitable would actually come from. No credible answers have been forthcoming. We know it cannot be the International Court of Justice, and we know that a case at the International Tribunal for the Law of the Sea would see the UK able to put forward a decent legal argument. Then the Government completely contradicted their own argument about the electromagnetic spectrum. They are planning to dissolve a strategically invaluable British overseas territory, and they cannot even tell us on what legal basis they are doing so.

It looks as though this is part of a wider sinister picture—the Government’s relationship with China. We know that the Government are desperate for Chinese investment to help grow our economy, which they are trashing with their reckless economic policies. The Deputy Prime Minister of Mauritius has credited China for its support in enabling Mauritius to gain sovereignty over the Chagos islands. Why? Because China wants to deepen its strategic partnership with Mauritius, which it believes to have strategic advantages. Once again, the Prime Minister does not have the backbone to stand up for our strategic interests against China. Amendment 7 would flush out the truth once and for all.

Taken together, amendments 3, 6 and 5 would delete a huge and unacceptable Henry VIII power that the Government are brazenly trying to award themselves, and would give this House the oversight it is entitled to on the implementation of the treaty. It is wholly unacceptable—in fact, it is quite outrageous—for the Government to give themselves such a sweeping power that they could, through an Order in Council,

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

This is a totally open-ended power. The military base itself is in scope, and so are the rights of Chagossians. The House should not be deprived of a voice on these matters of huge concern. Our amendments would ensure that this House has a voice and a vote. That is totally right and proper.

Turning to our new clauses, the Government could have inserted a money authorisation clause into the Bill. They chose not to and no wonder. The Government want to spare their own disgruntled MPs the ugly spectacle of having to vote in favour of spending tens of billions of their constituents’ money to Mauritius, as Britain’s economy sinks under the weight of the Chancellor’s inflation, unemployment, debt and taxes. Labour is asking the hard-pressed British taxpayer, already struggling under the weight of the Chancellor’s punitive tax rises, to stump up £35 billion to lease back a territory we already own and which we are not legally obliged to give away. As it leaves pensioners vulnerable and cold, destroys family farms and crushes businesses, the Minister is content to send our constituents’ hard-earned money to Mauritius with no strings attached, allowing the Government there to cut taxes—tax cuts over 6,000 miles away and tax rises at home. And Labour is inflicting this surrender tax on the British people because of its abject failure to negotiate. We all know that when Labour negotiates, Britain loses, but this is a new low. At seemingly every twist and turn, this Government have rolled over and capitulated to the demands of the Government of Mauritius.

[Graeme Downie]

The right hon. Lady mentions that she does not believe there is a legal basis. What was the legal basis for the previous Government, when they conducted 11 rounds of negotiation and achieved absolutely nothing?

[Wendy Morton]

I am not sure where the hon. Gentleman has been for the past year and several months, but we have gone over this time and again in this Chamber. There was no legal basis. We stopped—[Interruption.] Maybe I will repeat this very slowly for his benefit: we stopped the negotiations.
