Diego Garcia Military Base and British Indian Ocean Territory Bill

Jim Shannon Excerpts

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

[Jim Shannon (Strangford) (DUP)]

Thank you for allowing me to speak on this issue once again, Ms Ghani. I will prefix my comments with this. It is always good to see the Ministers—the Minister of State, Foreign, Commonwealth and Development Office, the hon. Member for Cardiff South and Penarth (Stephen Doughty) and the Minister for Defence Readiness and Industry, the hon. Member for Plymouth Sutton and Devonport (Luke Pollard)—in their place. They are both honourable men whose friendship I value. Being ever respectful, and with great respect to both hon. Gentlemen, I wish to make some comments that will be very contrary to what they have put forward today.

It will be no surprise that I rise at the last hour and as the last Back-Bench speaker—that is often the case, but none the less it is always a pleasure to make a contribution —to ask the Government again to reconsider their decision and ask the Committee to oppose the Bill, even though I know that the numbers game does not stack up.

As we all know, the treaty provides for Mauritius to exercise full sovereignty over the Chagos archipelago, with the UK exercising rights on Diego Garcia during an initial 99-year period. Over those 99 years, the UK will pay Mauritius a total of around £3.4 billion in 2025-26 prices, and that will probably rise. At a time when the Government are taxing farmers, taxing widows’ pensions and taxing the middle class into oblivion, handing over £3.4 billion with a benefit that is not tangible is unacceptable. Our constituents will be worse off in the next financial year. Indeed, a typical British family are as much as £15,000 a year poorer than they were five years ago, according to recent Telegraph Money analysis. Why, then, have we entered into this agreement, which may fluctuate and cost substantially more than the figure that has been predicted?

I want to make it clear that I believe this treaty should be renegotiated from beginning to end, but if the Bill is to go ahead, it is essential that any increases in payments should come through this House, and that whatever Government are in place at that time should present that. I therefore support new clause 1, which would give certainty and security that increases would not take place without the approval of this House.

Turning to new clauses 2, 5 and 7, I have long stated that there are now substantial risks to our military bases, and that has been reiterated by every person bar one in the Committee today. I am anxious to understand our legal standing on this. I believe it is right and proper for the Committee to understand the nature of how renting from Mauritius will give us the safety and security needed to ensure that those stationed on the base, or relying on support from the base in that area, will not feel vulnerable or exposed. I believe that this deal does expose us, and that we need to be very much aware of our standing and take the necessary steps. That begins with having full knowledge and not simply empty assurances. The recent debacle with the Chinese spies decisions has shown that openness, transparency and accountability are needed even more tonight than they have been in the other statements and urgent questions today. New clause 2 would enforce that as a minimum.

New clause 9 is similar to new clause 8, tabled by the hon. and learned Member for North Antrim (Jim Allister) and my right hon. Friend the Member for East Antrim (Sammy Wilson). I support new clause 9, given its similarity to the new clause brought forward by my Northern Ireland colleagues, who are intimately aware of how issues on the ground can be vastly different from those that are reported. This addition to ensure that a report is made on the compliance of the treaty and the Act with the UN General Assembly resolutions on decolonisation is vital and, I believe, underlines the words of support that have been given to those in the area who are fearful of the removal of British influence and support and fearful of the Mauritian ideals, which were flagged by our American allies in their human rights report in 2023.

As the chair of the all-party parliamentary group on international freedom of religion or belief, I know that the two issues of human rights and persecution are married together as one, because when we highlight the issue of human rights, we also highlight the issue of persecution of religious beliefs, and vice versa. I really have to express some concerns over human rights in this context. I understand that the Minister of State, Foreign, Commonwealth and Development Office, the hon. Member for Cardiff South and Penarth will reply to the debate. Although I believe he understands and believes in these issues as strongly as I do, I still have great concerns about human rights. It is essential that we do not simply hand over control and abandon not just the military base but all in the region who have relied on our support and friendship over the years.

Unfortunately, this has been a bad treaty from beginning to end. Our Chagossian citizens remain unhappy, our armed forces remain unhappy and the families who are footing the bill are unhappy. I believe that the Government have made the wrong decision on this. The recent Chinese debacle has heightened the need to continue to have boots on the ground and eyes wide open against those who would seek to thwart British interests and the interests of freedom and democracy worldwide. We have recently seen the result of appeasement when the Israeli Deputy Prime Minister highlighted the difficulties brought about by this Government’s decision to recognise terrorism and a Palestinian state with no borders, no working non-terrorist Government and no social care system. The handing over of Chagos and renting it back will prove to be a costly and dangerous exercise in capitulation, and even at this very late stage I urge the Government to think again and, at the very least, accept additional protection for the sake of all our collective security.

[Stephen Doughty]

I thank all hon. and right hon. Members for their contributions. I will attempt to respond to the specifics of the amendments and new clauses in due course, but I want to come back to some of the fundamental points that have been raised during the debate first, and I also want to respond to some of the specific questions that were raised.

With the exception of some genuine questions in relation to the Chagossians, the MPA and the environmental protections, and the implementation of this treaty, it was a shame to see the rehash of the same arguments that were made on Second Reading. There were some outrageous and nonsensical arguments and claims, particularly relating to the costs and to other matters, which I will come to.

I was shocked by some of the anti-American, conspiracy-fuelled nonsense that we heard at various points during the debate. The base is critical to the United Kingdom, the United States, our allies and our national security, and the Bill and the treaty protect the functioning of that base. It does not surrender it; it secures it into the future. This is a Government who inherited a mess from the former Ministers on the Opposition Benches. We are getting stuff done. We are a patriotic Government; our first duty is to protect the national security of this country, and that is why we have got this deal done. It is why it is backed by the United States. It is why it is backed by our Five Eyes partners. It is absolutely crucial to protect the British people and our allies.

We have been very transparent about the reasons for it, and they are the exact opposite of what has been suggested. I come back, as I always have done, to the fundamental question: if there were not a problem and a risk to the operations of this crucial base, why did the previous Government start the negotiations, why did they continue them through 11 rounds of negotiations, and why did they continue them right up until the general election? Those are the facts.

Diego Garcia Military Base and British Indian Ocean Territory Bill

Jim Shannon Excerpts

Consideration of Lords amendments
Tuesday 20th January 2026 Commons Chamber

[Priti Patel]

Let me say, for the benefit of everyone in this House, that the United States of America is our strongest ally when it comes to the national security of our country, and rightly so. When the President of the United States raises concerns, we should listen to them, and I would like to think that this Government will act on them.

Let me turn to the details of Lords amendment 5, which would introduce new provisions on transparency about the costs that British taxpayers are being forced to pay. It is vital that this House sees the full costs, as Labour has never acknowledged or accepted the financial costs and burdens of this Bill for the taxpayer. As the House knows, the Conservative party had to force the information out of the Government through freedom of information requests. Labour Ministers have had the bare-faced cheek to come here and give us their valuation of £3.5 billion, whereas the Government Actuary’s Department tells us that it is £35 billion.

In most areas of Government spending, Labour likes to brag about how much is being spent—welfare is a familiar theme that it likes to go on about—but on this issue, it is using a valuation technique to downplay the amount. We have heard the Prime Minister claim that this is

“how the OBR counts the cost”.

However, the Office for Budget Responsibility has said:

“The OBR does not hold any information on the costs or financial impacts of the specific treaty over the future sovereignty of the Chagos Archipelago. We can confirm that we have not been contacted by HM Treasury, MoD or the Governments Actuary’s Department”,

so what is the truth? This amendment would help to bring about more openness and transparency on the costs.

[Jim Shannon (Strangford) (DUP)]

I commend the shadow Minister and the Conservative party on this amendment, which is crucial. The key is whether the British Government have fully briefed the US about the risks to the Pelindaba treaty that will result from Diego Garcia becoming sovereign to Mauritius, because if they have, President Trump will be very glad to comment on that. Does she agree that the thing to do now might be to contact President Trump?

[Priti Patel]

The hon. Gentleman is right that that treaty relates to nuclear weapons coming on to the base at Diego Garcia. That is why our emphasis must be on the strength of the relationship between our two countries when it comes to our national security—this House will not disagree on that—but it is deeply concerning that the President of the United States has explicitly expressed his disapproval of this entire process and this giveaway. To address the hon. Member’s point about the nuclear treaty, we should absolutely be engaging with our closest ally, the United States of America.
