Diego Garcia Military Base and British Indian Ocean Territory Bill

Sammy Wilson Excerpts

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

[Graham Stuart]

The United States plays a critical role as a member of NATO and as a key ally—if not the key ally—of ours, but despite the priceless nature of the service it provides, we do not typically pay for it. We do not normally pay for its bases; we pay for our own.

[Sammy Wilson (East Antrim) (DUP)]

Will the right hon. Member give way?

[Graham Stuart]

I said I would give way to my right hon. Friend the Member for New Forest East (Sir Julian Lewis).

--- Later in debate ---

[Graham Stuart]

That is rather desperate. I give way to the right hon. Member for East Antrim.

[Sammy Wilson]

The Minister described this asset as “priceless”, yet he is giving it away—and not only is he giving it away; he is paying someone to take it! Is this the kind of decision people would expect from a rational Government? More importantly, if it is priceless in security terms, why are we compromising it?

[Graham Stuart]

The right hon. Gentleman is quite right to ask that question. That is what we are trying to get to the bottom of, and we hope to hear answers from the Minister this evening so that ordinary citizens of this country can understand how it is in the UK’s interest to do this.

Of course, other points have been touched on, including, quite rightly, the Chagossians. Why is the Labour party—the party so committed to human rights and which very much sees itself as champion for the underdog—absolutely disregarding the Chagossians? As the hon. Member for Bolton West suggested, Labour also sets itself out as a nature and climate champion, yet it is handing this asset over to a country without the wherewithal—I do not know about the will, but it is certainly without the wherewithal—to ensure that the protection of that marine area continues. That is the problem, and it is why we need answers from the Minister. The Government may be unable to get anyone to speak in favour of the Bill, but they should think again, accept the amendments and new clauses, and bring some light to bear on this rather murky issue.

[Blake Stephenson]

There is a difference between talking with other countries and doing a deal. I know that those on the Opposition Front Bench who formed part of the previous Government were not going to do this deal. They may have been talking, but as we have heard, there was going to be no agreement. I thank the hon. Member for his intervention and reflecting that I was not part of the previous Government, but he knows full well that this agreement would not have been made under these terms if the Conservatives were in government now.

The marine protected area is one of the largest untouched marine ecosystems, and it is globally significant. As such, instead of heedlessly driving this hopeless surrender deal through Parliament, the Government should have been ensuring that protections for wildlife and the marine environment were watertight. When answering questions before the Foreign Affairs Committee in June, the Minister would not give any clear assurances or guarantees on the future of the marine protected area. Within his obfuscation about separate agreements with Mauritius, which hope we can “share objectives and values”, he admitted that we can only

“take it on trust that there will be a Marine Protected Area”

after sovereignty has been surrendered.

We absolutely do not need to take that on trust. The Government have failed to secure any meaningful safeguards or guarantees, and are instead hoping—merely hoping—that a memorandum of understanding will somehow protect that pristine ecosystem. How on earth can we have any confidence in that at all?

A simple change of Government in Mauritius, or even just a change of heart, would render the UK powerless to stop Chinese trawlers turning up and devastating the marine environment. Given the evidence of China plundering the high seas, for example in the south Atlantic, just outside the Falkland Islands zone of economic interest, it absolutely will do the same in that territory.

[Sammy Wilson]

The hon. Gentleman is making a powerful point about the marine environment in the area, but does he accept that we do not even need a change of heart by Mauritius? We do not need it to decide that the treaty was not worthwhile—it does not have the ability to give the protection. Even if there was no change of heart, there is no ability to give such protection, which is why this is a bad deal for the environment.

[Blake Stephenson]

I absolutely agree, and I note that the right hon. Gentleman and I are the only Members in the Chamber from the Environmental Audit Committee, which I think is a damning indictment on those Members in this House who are here to protect our environment and hold the Government to account on environmental protections.

Will the Minister now explain what will happen to the MPA in future, and say whether the Government will commit resources to support the protection of the MPA? If so, where will those resources come from? With the fisheries Minister of Mauritius talking of issuing fishing and trawler licences, it is more important than ever that we have lasting confidence in marine protections before British territory is surrendered to Mauritius. When the Minister sums up the debate, will he say whether he shares my concerns over new fishing and trawler licences?

New clause 3 would require that any written instrument on the establishment and management of the marine protected area be subject to the approval of this House to ensure that it is fit for purpose. Will the Minister say what progress has been made with developing the “separate…instrument”, referenced in article 5.2 of the treaty? Will it be in place before Mauritius assumes sovereignty? Any agreement on the Chagos MPA must be scrutinised like a treaty and presented to Parliament.

New clause 4 would require the Secretary of State regularly to report on the status of the marine protected area. Reports from Committees in the Lords have raised concerns about Mauritius’s track record on environmental protections. Does the Minister agree with those concerns, and therefore agree that the ecological status of this extraordinary environment must remain on the British Government’s agenda, and will he reflect on that in his summing up of the debate? Will he now accept that, as well as costing British taxpayers £35 billion, betraying British Chagossians and undermining our security, without better protections secured in the treaty, the Government’s Chagos surrender deal will harm the marine environment? All of this at a time when the Government argued that the state of public finances required tough choices—choices that punished pensioners, family farmers, and taxed education for the very first time.

The annual cost of the surrender of the Chagos islands could pay for 3,068 new teachers, 3,253 new nurses or 1,975 police officers. In the first year, the money paid to Mauritius could deliver a new GP surgery in 30 communities —communities such as Wixams and Wootton in my constituency of Mid Bedfordshire, which are still waiting for improved access to local healthcare. This was all a choice—a choice to prioritise ideological surrender over our communities, over our security, and over marine protections. It is shameful, and I encourage hon. Members across the House to support new clauses 3 and 4.

[Ben Obese-Jecty (Huntingdon) (Con)]

For no apparent reason, and in a crowded field, the Government have chosen the Chagos islands as one of the many hills they wish to die on. The surrender of the sovereignty of the Chagos islands has been a puzzling mis-step for months, with today’s votes the culmination of it.

There was a clumsy rush to try to force the deal through, first before the elections in Mauritius and then before the US elections, and there now appears to be an attempt to salvage some dignity, having seemingly surrendered

“meekly to a Mauritian shakedown”,

as my right hon. Friend the Member for Tonbridge (Tom Tugendhat) has put it, while trying to upsell the deal to a US Government that publicly backs it, given that it will not cost them a penny, but privately must have concerns over the impact of allowing Chinese encroachment in the region. With recent developments shifting the focus of US foreign policy to the Indo-Pacific, the Chagos islands deal surely takes on greater significance. The base is now more important to US policy, not less.

Last December, the previous Armed Forces Minister, the hon. Member for Plymouth Sutton and Devonport (Luke Pollard), who is in his place, announced that the deal

“secures the future of the UK-US base on Diego Garcia”,

and said that

“when everyone looks at the detail of the deal, they will back it”.—[Official Report, 2 December 2024; Vol. 758, c. 28.]

Indeed, the Minister for the Overseas Territories, the hon. Member for Cardiff South and Penarth (Stephen Doughty) confirmed to me that

“There has been no change to the substance of the deal”.—[Official Report, 5 February 2025; Vol. 761, c. 764.]

That is strange, because the new Prime Minister of Mauritius, Navin Ramgoolam, described the deal struck with the previous Mauritian Government as a “sell-out”, stating that the deal should be indexed to inflation, take exchange rates into account and fully recognise Mauritius’s ownership of the islands, which could affect the UK’s unilateral right to renew the lease. That was in mid-January. Less than a fortnight later, the Minister confirmed to me in a written answer that the UK would not have the unilateral ability to extend the agreement at the end of the lease. What changes were made to the original deal during discussions with the Government of Mauritius, and why have the Government gone on record as saying that the deal has not changed, in direct contradiction with the statements of the Prime Minister of Mauritius? Surely the Minister for the Overseas Territories is not suggesting that Prime Minister Ramgoolam is mistaken.

In January, when I asked the Prime Minister whether he had ever discussed the Chagos islands with Philippe Sands KC, his answer was a brusque, “No.” Brevity is key when trying not to give too much away. Philippe Sands has represented Mauritius at the International Court of Justice in multiple disputes over the Chagos islands. In 2022, Mr Sands published “The Last Colony: A Tale of Exile, Justice and Britain’s Colonial Legacy” about Chagos. It is worth highlighting that Philippe Sands and the Prime Minister have apparently been very good friends for several years; they even interviewed one another at the Hay festival.

Earlier this year, The Telegraph reported that the national security justification for surrendering the Chagos islands used by the Prime Minister came from Philippe Sands, who wrote about it in the 2023 book, “The International Legal Order in the 21st Century”. With Mr Sands apparently no longer representing Mauritius following the change in regime, it does make one wonder if that was the reason why there was such a rush to conclude the deal before the election, after which Mr Sands’ services were no longer required—did the Government lose their in?

I would be interested to know how the Government think the International Telecommunication Union would block our use of the electromagnetic spectrum. How would it block communications equipment on Diego Garcia without encroaching on our territory? What active blocking of electromagnetic frequencies is a UN agency capable of doing anyway? What steps would the ITU have taken to block the US military’s use of the electromagnetic spectrum had we not progressed this deal? The national security argument simply does not stack up.

New clause 6 would require the Secretary of State to report annually to Parliament on the impact of UNCLOS on the operation of the treaty. The Government have previously stated that it is ITLOS that would pose the greatest threat to the operation of Diego Garcia. It was cited specifically by the Defence Secretary for the first—and only—time on 22 May, when he said:

“There are a range of international legal challenges and rulings against us. The most proximate, and the most potentially serious, is the International Tribunal for the Law of the Sea.”—[Official Report, 22 May 2025; Vol. 767, c. 1291.]

In July, the Minister for the Overseas Territories referred to ITLOS for the first time since he was a shadow Minister for Foreign, Commonwealth and Development Affairs, when, in December 2022, he had stated that the International Tribunal for the Law of the Sea

“did not have competence on territorial disputes”,

going on to say:

“It is a fact that China has made increasing encroachments into the territorial waters of its neighbours and vast claims in the South China sea while ignoring judgments against itself. That has been matched by a growing assertiveness, and even belligerence, towards some of our allies and partners in the region”.—[Official Report, 7 December 2022; Vol. 724, c. 162WH.]

He asked for assurances then. Now, nearly three years later, with a belligerent China flexing its naval muscle in the region and adopting a robust posture towards us over the delay to the decision on its London embassy and the obvious ongoing spy debacle, what assurances can the Government give the Committee that this opportunity will not be exploited by the Chinese Communist party?

As recently as August, the Mauritian Government referred to

“The strategic role of Mauritius as an investment gateway to Africa and a trusted partner for Chinese enterprises seeking to expand their footprint therein”.

Mauritius is committed to working closely with China—far closer, it would appear, than it is to working with us. Why are the Government prepared to embolden Chinese ambition in the Pacific? Why are they prepared to embolden Chinese spying in Parliament? Why are they prepared to allow the Chinese to build an embassy in London without absolute clarity on its structural plans? With all that in mind, why will the Government not include China in the enhanced tier of the foreign influence registration scheme? The shadow of Jonathan Powell looms large over this deal, as it has over every aspect of the Government’s dealings with the Chinese Communist party.

Across the globe, we are seeing changes in the rules-based order. We must navigate this better. My fear, which is shared by all on the Conservative Benches, is that this capitulation shows no understanding of the changes we are facing. We need to ensure that this great nation stands up for safety, freedom and security across an increasingly dangerous world, and this opaque and furtive deal puts that at unacceptable risk.

[Sammy Wilson]

A deal of such implication, one would have thought, would have been hotly debated in this House, yet as has been pointed out, there has been no attempt to defend it by the Government. In fact, one could hardly call this a debate—it has all been one-sided. In a debate, people usually argue in favour of whatever the proposal happens to be and listen to and rebut the arguments from the other side. We have had no rebuttal from the other side—the Government—today, despite the fact that this is such an important deal.

For some people outside the House, this deal might seem to be an unimportant issue—where are the Chagos islands, and why do they matter? However, even if the attitude taken by Government Members is to say, “Our constituents are not all that interested in the issues around the Chagos islands,” there are issues with this deal that have been raised this evening that should concern them all.

Let us look at the issues, because they are addressed by the amendments. The first is human rights—the human rights of the people who were displaced in the 1960s and who are ignored in this deal. Their rights to self-determination and to decide where they live are being ignored, yet we are not getting any response from the Government—the party that talks about human rights all the time. They say that we cannot leave the European convention on human rights because human rights are so important, but they are ignoring the human rights of the people who are affected by this deal.

[Stephen Doughty]

Will the right hon. Member give way?

[Sammy Wilson]

Since we are going to have a debate, I will listen to the Minister.

[Stephen Doughty]

I thank the right hon. Member for giving way. He says that he wants a debate, and I have given a number of rebuttals. He mentions the Chagossians, whom I will come to in my concluding remarks. I respect what he has to say, but I point him to remarks from the Chagos Refugees Group, which said in its communiqué to all of us: “We urge all Members of Parliament to support the Bill at its final stages and deliver long overdue justice to all our people. Passing this Bill will mark a turning point and the moment when Parliament stands on the right side of history and begins to restore what was unjustly taken from us.” There are a range of views within the Chagossian community, and I think it is important that those are put on the record.

[Sammy Wilson]

Of course there are many who take a totally different point of view and whose wishes are not reflected in this Bill. The amendments that have been tabled to seek to remedy that situation are being ignored and opposed by the Government.

The second issue is the economy. On a regular basis, we hear how difficult the fiscal position is for this country—black holes we have to fill by taking money off pensioners, reducing benefits, cutting here and cutting there, and taxing people to the hilt. Yet when amendments are tabled that simply request transparency and the opportunity to look at the expenditure involved in this treaty, we hear no support from the Government. Either we are concerned about the fiscal position of this country or we are not. I would suggest that £35 billion—and rising—is a significant figure that we should be looking at.

[Dr Luke Evans]

The right hon. Member is making a powerful point. Is not part of the problem that we do not even know which budget the money is coming out of? That is the kind of simple question that the man or woman on the street would expect us to be able answer.

[Sammy Wilson]

We may not know which budget it is coming from, but we know whose pockets it is coming from: the pockets of taxpayers. To a certain extent it does not really matter, because all our constituents will pay for this deal. The Minister said that the Chagos islands were priceless, yet we are giving them away and giving away taxpayers’ money for them—and we do not even know how much we will be giving in the long run. I would have thought that some Government Members have concerns, if not about human rights then about the financial implications of the deal.

Especially at this time, national security is an important issue for every Member of the House, yet amendments that seek to ensure that there is scrutiny over what happens to these islands, who has influence in them and whether the treaty that has been entered into guarantees that our security will not be jeopardised are being refused. The Government are not even attacking the amendments or explaining their opposition.

[Paul Holmes]

Does the right hon. Member share my dismay that, despite a Government majority of over 170 and the fact that there are over 400 Government MPs, on an issue of national security only one Government Back Bencher spoke in this debate? Does he think that is an indication of how the Labour party views national security and an overseas territory being given away for nothing?

[Sammy Wilson]

I do. Since the hon. Member has given me the opportunity, I will make the point now—I was going to make it later on—that while no Government Members have been rushing to defend the Bill in the Committee, hundreds of them will be rushing through the Lobby at 10 o’clock or half-past 10 to vote for it. That is the worrying thing. Defence of it, there is none; support for it, despite the issues we have highlighted, there will be.

--- Later in debate ---

[Phil Brickell]

Will the right hon. Member give way?

[Sammy Wilson]

I will in a minute, but let me finish this point. Yet here we have a Bill that does not give any long-term security to one of the pristine marine environments. Indeed, we are handing over responsibility for it to a Government who could not even get a boat to put a flag up, yet we are supposed to believe that they will be able to protect the marine environment if foreign countries attempt to destroy it by doing deep-sea trawling, bottom trawling and so on. I would have thought that the environmentalists on the Government Benches might at least have asked some questions about the treaty, or would have supported some of the amendments that seek to do that, yet we find that is not the case.

This is a bad Bill. It will have long-term implications for our country financially and it will have long-term implications for those people who felt that perhaps there was an opportunity for their rights to self-determination to be granted. They have not been. Of course, there are also dangers to our long-term security.

I will finish with this point. I have no doubt that the Minister will repeat the point he made. Sure, the Americans support it—as if the Americans always make good strategic decisions. They do not. Given the time tonight, I know that you would stop me, Madam Chairman, if I started going through some of the bad strategic decisions the Americans have made that we and the world have lived with and their consequences. Just because the Americans—for short-term gain or short-term interest—have supported the deal, let us not say it is okay. It is a bad deal. Amendments were made to try to improve the Bill. The shame is that those amendments were not debated. The Bill goes contrary to the beliefs of many Members on the Government Benches. Unfortunately, I suspect the Bill will go through with a huge majority.

[The Chairman of Ways and Means (Ms Nusrat Ghani)]

For the final Back-Bench contribution, I call Mr Jim Shannon. If people have contributed, they should make their way back to the Chamber. Danny Kruger, I am looking at you to whip your colleague.
