British Indian Ocean Territory

Debate between Iain Duncan Smith and Priti Patel

Wednesday 28th January 2026 Commons Chamber

[Priti Patel]

The hon. Member is absolutely right, and he speaks to my fundamental point about capitulation, surrender and the way that the Government have worked against Britain’s interests. We see that night and day, and it is unforgiveable.

[Sir Iain Duncan Smith (Chingford and Woodford Green) (Con)]

My right hon. Friend is making an excellent start to this attack on the Government, but I will ask her a simple question. Should we not also dig a little deeper on the links between the Prime Minister and some of his earlier colleagues? That way, we would learn that Phillipe Sands, who was representing the Mauritian Government, had a deal done with the Russians over Crimea, in which he assured them, I understand, that the granting of independence and ownership for Mauritius would not impinge on their right to stay in Crimea. That was what brought their vote, and their support for this deal. Does that not look to my right hon. Friend as though it was absolute method traitorship?

[Priti Patel]

My right hon. Friend has made his point very clearly. This Government are not standing up for our values or interests. Nor are they making any effort to demonstrate that they are on the side of our national security. Fundamentally, that is what this debate is all about.

It is diligent work and scrutiny by Conservatives in this House and the other place that has led to the Government being forced to pause this surrender. That has been achieved by our diligent diplomatic engagement with the US Administration, by asking for over 400 parliamentary debates, by securing two Opposition day debates, and thanks to you Mr Speaker, by asking urgent question after urgent question. We are here to demand answers that they never provide, but only hide, all thanks to their shameful outright contempt for Parliament and the British public.

The Opposition have proudly made representations on behalf of the Chagossian people, who have not only been betrayed but are being threatened in Britain. Their families are being intimidated by people associated with the Government of Mauritius, who seem to be learning how to conduct transnational repression from their friends in the Chinese Communist party. This Labour Government will go down in history for many terrible things, but they can now add to that list of shame the repression and betrayal of the Chagossian people. Labour must rethink its deeply corrosive policy, which is putting at risk our security and the safety of the Chagossian people. Instead, we have a weak and feeble Prime Minister, currently on his knees in Beijing, who will do anything possible to push through this deal—a deal that has been constructed and negotiated by his left-wing international lawyer friends, whose views he seems to value much more than the British people and the Chagossian community.

We all know how this has gone completely wrong, although the Prime Minister could still take a different course. It has gone wrong because this surrender is completely unnecessary—because, as the Opposition know, it is based on an advisory opinion. Ministers have failed to give a convincing answer as to why we should accept it, and there is no answer on what enforcement mechanisms would exist, other than some hypothetical comments about the electromagnetic spectrum and the International Telecommunication Union. So tell us today, please.

We have not only a Government of incompetent politicians, but a Government of incompetent lawyers. In the words of President Trump, Labour is surrendering sovereignty “for no reason whatsoever.” Given this Labour Government’s obsession with international law, it is surprising and shocking that they are not just misinterpreting it, but have overlooked essential detail in the 1966 UK-US exchange of notes. This is now the third time I have brought the exchange of notes to the Dispatch Box in just the last week, Mr Speaker. For the avoidance of any doubt in the House or any ignorance on the Government Benches, the 1966 treaty with the USA, which establishes the military base on Diego Garcia, states that the whole of the British Indian Ocean Territory

“shall remain under United Kingdom sovereignty.”

It goes on:

“Subject to the provisions set out below the islands”—

all the Chagos islands, not just Diego Garcia—

“shall be available to meet the needs of both Governments for defense”.

This is a legally binding treaty between the United Kingdom and the United States of America on the British Indian Ocean Territory, and any attempt by the UK to surrender sovereignty over BIOT violates international law. Yet when the Government signed and published their treaty on 22 May last year, and then published their surrender Bill, there was not a single mention in either the treaty or the Bill of the need for the exchange of notes.

On Monday, in response to our urgent question, the Minister for the Overseas Territories, the hon. Member for Cardiff South and Penarth (Stephen Doughty), said:

“we have been clear throughout that before the UK can ratify the treaty, we will need to do the following: pass primary and secondary legislation; update the UK-US agreement—the exchange of notes; and put in place arrangements on the environment, maritime security and migration”,—[Official Report, 26 January 2026; Vol. 779, c. 599.]

but this was not mentioned in any of the documents accompanying the legislation, let alone the treaty. When we have questioned this in both Houses, Ministers have merely said:

“Talks are ongoing to update the UK-US Exchange of Letters”,

but the exchange of notes was not even referred to in any of the documents accompanying the legislation.

I think this House deserves an explanation. When did the talks begin? What is the status of the talks? What is the timescale for making changes? Have the Americans raised concerns that the exchange of notes were not part of the original discussions with the US Government last year, when the Prime Minister said that the US supported the treaty? Why did the Government try to force through their surrender Bill without confirming the future of the exchange of notes?

Tuesday 9th September 2025 Commons Chamber

[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.

Debate between Iain Duncan Smith and Priti Patel

Wednesday 26th February 2025 Commons Chamber

[Priti Patel]

My right hon. and learned Friend absolutely speaks sense on this issue and that is exactly why I enjoyed working with him so much on some of the challenges we faced in government. That is exactly the point.

Turning to the substance, or proposed substance, in the proposed treaty, the Labour Government failed to provide any transparency over plans, but we are fortunate that the new Prime Minister of Mauritius, Navin Ramgoolam, and his Government have been much more open and candid about the negotiations, sharing the details of the humiliating concessions that Labour Ministers have made in this epic failure of diplomacy.

[Sir Iain Duncan Smith (Chingford and Woodford Green) (Con)]

I just wanted to prompt my right hon. Friend to pursue one other matter, which is quite important. I was looking at the list of the judges who sat on the ICJ panel. It is quite interesting. Apart from there being a Russian who was fully supportive of the invasion of Ukraine, it turns out that Vice-President Xue, who wrote the whole case, also voted to support the Russian invasion of Ukraine and was heavily involved in the Chinese Government previously. To what degree does that represent balanced and informed judgment—here internationally—as we would have in the UK?

[Priti Patel]

My right hon. Friend is spot on and makes a point that I have made. There are people—judges in particular—who clearly are undermining our integrity, sovereignty and the decision making in our own Government. They are pursuing their own interests and that is why we have to call out this deal.

--- Later in debate ---

[Priti Patel]

My right hon. Friend is absolutely correct. Sovereignty matters, and the Minister could not admit it to the House yesterday in the Chamber, but perhaps when a Minister sums up today they can confirm that change in position. We need to know whether we have lost sovereignty and lost control.

Fourthly, it is clear there has been a change in the lease agreement—this letter makes that crystal clear. When the Foreign Secretary made his statement to the House on 7 October 2024, he stated that the lease

“is initially for 99 years, but the UK has the right to extend that.”—[Official Report, 7 October 2024; Vol. 754, c. 46.]

The impression given was that this could be unilaterally extended, as he would not say at the time that both parties needed to agree.

[Sir Iain Duncan Smith]

The reality is that the present Prime Minister of Mauritius has publicly stated—by the way, he also mentioned that the cost would be up to £18 billion—“Interestingly, we would have happily looked at joint sovereignty where it was clear, but the British Government did not want it.”

[Priti Patel]

My right hon. Friend is absolutely correct, and I am afraid it shows the lack of commitment to even understanding the sovereignty of the territory.
