Diego Garcia Military Base and British Indian Ocean Territory Bill

Baroness Foster of Aghadrumsee Excerpts

Committee stage
Tuesday 18th November 2025 Lords Chamber

I ask the Minister to clarify that. I think that these amendments, tabled by my noble friend Lord Lilley, go to the heart of this whole discussion. I am very supportive of them.

[Baroness Foster of Aghadrumsee (Non-Afl)]

My Lords, I first declare my interest as a Friend of the British Overseas Territories. I support the noble Lord, Lord Callanan, in his efforts to bring clarity to the Bill, at the very beginning of the Bill.

I particularly endorse the comments of the noble Lord, Lord Lilley, in relation to his amendments. It was in the conversation about those amendments that the issue of self-determination came up. I know that we are going to talk about self-determination in relation to amendments later on in Committee. However, there is a fundamental point about self-determination. The noble Lord, Lord Grocott, asked whether we would ever cede British territory. Well, of course we have, when we have had self-determination exercised. In this case—the Minister went through this in some detail in Second Reading, because I raised it—it is deemed not applicable to the British Indian Ocean Territory.

We all received a letter today from 650 members of the Chagossian community here in the United Kingdom. In that letter they say:

“To do so, however, in the context of re-denying the people concerned self-determination while simultaneously paying a country that played a key role in denying that people self-determination in relation to their territory on the previous occasion, more money than is required to resettle the people with the rightful claim to the territory, in order to lease one of their islands, demonstrates extreme moral disorientation”.


I completely agree with that.

I also completely agree with the second point that the noble Lord, Lord Grocott, made on resettlement. We all heard at Second Reading that there had been an exercise looking at resettling Chagossians into the Chagos Islands. Back in 2015, the KPMG report gave the details of the costs and the then Government decided not to proceed, probably based mostly on cost. But now the costs we are paying to the Mauritian Government far exceed the costs of resettlement. There is an opportunity for some Chagossians, if they wish, to resettle on Diego Garcia. In other British Overseas Territories there are civilians on military bases: Ascension Island comes to mind. So it could be the case that it happens in Diego Garcia as well. We will touch on resettlement rights and the right to return in other amendments, but, given that it was raised in this context, I just wanted to make those couple of points. I support the amendments in this group.

[Lord Hannan of Kingsclere (Con)]

My Lords, I will start with the amendment from my noble friend Lord Callanan and the objection to it from the noble Lord, Lord Purvis of Tweed, which was that this wasincompatible with the decision taken by Parliament. I will just quote—because I think it is helpful—Article 18 of the treaty. It states:

“This Agreement shall enter into force on the first day of the first month following the date of receipt of the later note by which the Parties notify each other that they have completed their respective internal requirements and procedures necessary for the entry into force of this Agreement”.


In other words, it cannot enter into force until both Chambers of this Parliament have given their assent.

We have not made any bones about the fact that we do not like the treaty at all. I think it is a bit much to complain about my noble friend making this point in principle.

--- Later in debate ---

The reason why we are here discussing this—let us be blunt—is the influence of a cabal of lawyers operating between Doughty Street Chambers and Matrix Chambers. They became so obsessed with the technical legal arguments, the rules-based world and territorial integrity that the Government have been persuaded by them, lost sight of the big moral picture and let the country down. The chief protagonists of course—I do not need to mention them again—are Philippe Sands and the Attorney-General. This argument about the legal issue that I have already mentioned does not wash with me when it comes to something so morally important as what we are doing to the Chagossian people. The public see just how shamefully this Government have behaved. I am very sorry that it has come to this. I hope that as a result of this discussion, this debate and the myriad amendments, even at this late stage, the Government might realise that they have gone too far, too quickly and are doing down the Chagossian people and, more importantly, even their own morality in the way they have behaved.

[Baroness Foster of Aghadrumsee (Non-Afl)]

My Lords, I want to speak briefly on this group. I support a number of the amendments in it, in particular those that call for a referendum for the citizens of the British Indian Ocean Territory—that comes as no surprise, I am sure, given my Second Reading speech—Amendment 37 in the name of the noble Lord, Lord McCrea of Magherafelt, asking for Chagossian representation to liaise with Parliament and Amendment 49, also in his name, adding a new clause for the assessment of Chagossian civic identity and self-determination.

The treatment of the Chagossians in 1965 is being exacerbated by their treatment today by this Government —I think that is a fact. We have talked at length about the lack of consultation and the great haste with which this treaty came about. That has led to claim and counterclaim about how Chagossians feel about the transfer of sovereignty. Surely the simplest way to find out the answer is to hold a referendum among those who hold BIOT citizenship. As I said at Second Reading, geography is not political destiny, especially when the closest country to Diego Garcia is not even Mauritius but the Seychelles. Given the past treatment, taking the views of the Chagossian community is now the very least that this Government should do.

Until now, Chagossians living here in the UK have been pushed aside, as I said at Second Reading, even by their Members of Parliament. That is astonishing. We are supposed to live in an open democracy where Members of Parliament are voted in to the other place and are responsive to people who live in their constituencies. It is dreadful that despite repeated requests to meet in person, they have been rejected. As I said at Second Reading, if you are a Member of Parliament and you are going to vote through a government policy, the very least you should do with your constituents is have the wherewithal to meet them and explain why you have supported the position of the Government. I do not think that is rocket science.

[Lord Horam (Con)]

I should just correct the noble Baroness. When Mr Henry Smith was the Conservative MP for Crawley, he listened very carefully to the people in his constituency. He was also an active member of the APPG on Chagos, of which I am a member.

[Baroness Foster of Aghadrumsee (Non-Afl)]

Yes. I am not speaking about Henry; the noble Lord is absolutely right. I shared a platform with him at a Chagossian event a number of months ago. However, this is direct testimony from my Chagossian friends, who have been very clear about a number of MPs whom they contacted, and they were not listened to and were refused a meeting.

Treating our fellow Britons—that is how I see my Chagossian friends—with dignity and addressing their needs are very important. It certainly does not mean that we are challenging national security issues. The two can and should exist together. Just because we have a marvellous asset in Diego Garcia—I am not suggesting otherwise—for our national security needs and those of our friends and colleagues in the United States of America does not mean that we cannot also have a conversation with Chagossian people about their rights, aspirations and needs. The two can and should exist together.

I have already mentioned that the KPMG report of 2015 on the feasibility of the resettlement of BIOT indicated that

“there are no fundamental legal obstacles that would prevent a resettlement of BIOT to go ahead”.

Of course, that is what the Government of the day should have done. They decided not to, citing cost concerns, but how cost effective and value for money does that not look today when we consider the costs of this treaty and the money that we are going to be sending to the Mauritian Government?

Despite what previous Mauritian Administrations have said, the Chagos people are a distinct people on the basis of ethnicity, culture and religion and should be afforded respect by being asked how they view the transfer of sovereignty of their homeland. If this Government turn their face, as it appears they will, against a referendum, they should pay heed to the referendum carried out by the BIOT citizens, which many friends and colleagues in the House have referred to, because that shows a staggering 99.2% of Chagossians who were polled supporting UK sovereignty over the Chagos Islands.

Chagossians have had to resort to press releases and court challenges to be heard, and it is now long past the time for the Government to step back and put in place a referendum to listen to their voices.

[Baroness Hoey (Non-Afl)]

The noble Baroness said 99.2%—I got it wrong; I said only 99%. Does she think that one of the reasons, or perhaps the reason, that the Government will not even contemplate a referendum of the Chagossian people is that they know that they would get the wrong answer and therefore they would be even more morally bound to tear up this Bill and the treaty?

[Baroness Foster of Aghadrumsee (Non-Afl)]

I pay tribute to my friends in the Chagossian community for raising their voices, which have been very loud. As I said, they have had to find other means by which to raise their voices, whether that be through court challenges or press releases.

I think the Government are well aware of how a number of Chagossians here feel about this. As my noble friend has already alluded to, we have heard that there are Mauritians who are in favour of this deal. I have no doubt that there are those from a Chagos background living in Mauritius now who are in favour of the deal—that is accepted—but I believe that the greater number of those Chagossians want to remain British citizens.

I also support Amendment 37 in the name of the noble Lord, Lord McCrea of Magherafelt and Cookstown, which, as an alternative to a referendum, asks for a Chagossian representative to liaise with Parliament. I know that other later amendments coming up, including from the noble Lord, Lord Purvis, look at ways to be creative about hearing the voice of Chagossians. I commend the noble Lord, Lord McCrea, on mentioning individual names. We are talking about communities but, actually, these are individuals who feel very passionately about their homeland; it is important that we remember that.

Finally, Amendment 49 seeks an assessment of Chagossian civic identity and self-determination, again seeking to underline the distinct nature of the Chagossian people. I support that amendment as well. This has been a good debate but, for me, it is really important to listen to the voices of the Chagossian people.

--- Later in debate ---

[Baroness Chapman of Darlington (Lab)]

My Lords, it is worth restating—and many of the contributions this afternoon have stated this too—that this Government deeply regret the way the Chagossians were removed from the Chagos archipelago. If I can commend just one speech that we have heard in consideration of this group, it would be that from the noble Lord, Lord McCrea. I found that an impactful, passionate speech that was sincerely given and heartfelt. I do not think I am going to make him happy this afternoon, but what he said was sincerely felt and I respect the way he put his argument and many of the things he said.

We remain committed to building a relationship with the Chagossian community that is built on respect and an acknowledgement of the wrongs of the past. I know—and I agree with much of what has been said—that this House clearly feels very strongly about Chagossians and ensuring that their views are properly heard. We have agreed that the International Relations and Defence Committee will undertake an important piece of work looking at Chagossian views on the treaty. We are looking forward to its report and I am sure we will all read it with great interest.

Turning to the arguments we have just debated, Amendments 13 and 28—I think the noble Lord said he was degrouping Amendments 14, 25, 64 and 84—all relate in some way to holding a referendum or some sort of consultation with Chagossians on the transfer of the Chagos archipelago to Mauritius. I know we have said before—there will be some repetition of argument on these issues—that in the negotiations on the treaty between the United Kingdom and the Government of Mauritius, our priority was to secure the full operation of the base on Diego Garcia. I accept that there will be those who disagree with that priority.

The Chagos archipelago has no permanent population and has never been self-governing. Therefore, on the question of self-determination for its population, the English courts have, noting the conclusion of the ICJ in the 2019 advisory opinion, proceeded on the basis that the relevant right to self-determination in the context of BIOT was that of Mauritius rather than of Chagossians. That feels incredibly cold and hard to read from this Dispatch Box, but that is the situation legally as determined by English courts. I do not think it helps anybody, not least the Chagossians, to somehow pretend that that is not the case. That is the situation we are in. We can regret that, we can argue about it, we can say that should not be the case; but that is the legal reality.

In a series of judgments since the 1970s, both the English courts and the European Court of Human Rights have also considered the related but distinct question of an alleged right of abode or other rights that are said to flow from that. On each occasion, the English courts and the European Court of Human Rights have ultimately dismissed the claims. The transfer of sovereignty therefore does not deprive Chagossians of any existing right. This is a long-standing legal position that previous UK Governments have also adopted.

[Baroness Foster of Aghadrumsee (Non-Afl)]

The Minister is repeating what she said at Second Reading, and I acknowledge that that is the case. I said to her then that while the courts have taken a particular view in relation to this matter, it does not rule out Parliament taking a different view, given that we believe in parliamentary democracy and parliamentary sovereignty. Given the way in which this community has been treated for 60 years now, it is fair to say, do we not have a moral obligation to accord them the right to have a say? Regardless of the fact that there have been court judgments on this, can we as not parliamentarians indicate that we believe that the best way forward is to listen to their voices?

[Baroness Chapman of Darlington (Lab)]

I think we can. I do not think we can call it self-determination in the legally applicable sense, but I agree, and I think Parliament agrees too, that the Chagossians deserve the respect of a different kind of relationship with the UK Government, and we need to make sure that we engage with them in a respectful and meaningful way. I will get on to whether that means a referendum, but the noble Baroness makes a very strong point about the importance of listening to the voices of Chagossians themselves, however we might choose to do that. I have mentioned this being a long-standing legal position, but as I am trying to explain, we recognise the importance of these islands to the Chagossians, and we are working hard to reflect this in our wider policies, not all of which are reflected in the Bill because they do not require legislation.

Given that the treaty has been signed, however, and the Bill is reasonably well advanced, having been through the other place, I say with great sincerity that any formal consultation at this stage would not be honest or sufficiently meaningful. I think that was what the noble Lord, Lord Purvis, was gently trying to point out to us, because that window was open at one point. It was open when the now Opposition were in government, and they never decided to consult the Chagossians. We agree with that Government, as they were—now the Opposition—that there is no actual legal duty in this situation to do that, but it is vital to respect the many different views within the Chagossian community, including that of several groups that welcome the deal.
