Diego Garcia Military Base and British Indian Ocean Territory Bill

Baroness Chapman of Darlington Excerpts

Tuesday 25th November 2025 Lords Chamber

To govern is to choose. The Prime Minister has made a choice: to stand with his learned north London, prosecco-drinking friends, against the wishes of his plain-talking, pie-and-pint caucus in his wider party and the wider interests of the British people and our kinsmen on the Chagos. This is a bad Bill and we should fight it as hard as we can.

[The Minister of State, Foreign, Commonwealth and Development Office (Baroness Chapman of Darlington) (Lab)]

My Lords, I was not sure whether anybody else wanted to follow that last speech. I do not think I have ever seen the Prime Minister drink prosecco—he would prefer a pint, I think.

Anyway, I thank noble Lords for their speeches on this quite important set of amendments, and I would be very surprised if we did not come back to some of these issues on Report, because, for all the nonsense we have just heard, there are actually some very thoughtful and quite important considerations here. Someone put it very well when they said that, while they might not agree with everything we are doing, there is a shared view across the House that we need to do as best we can through this process for the Chagossian communities.

Regarding Amendments 17, 26 and 78, the Chagossians are already entitled to work on the base and have done so. There are a range of job opportunities on Diego Garcia, open to Chagossians with British, Mauritian and Seychelles citizenship. A link to vacancies advertised by KBR, the main contractor responsible for recruiting and managing support staff at the base, is already available on the GOV.UK pages, setting out UK government support for Chagossians. On Amendment 78 from the noble Lord, Lord Hannan—

[Lord Bellingham (Con)]

How many Chagossians are actually working on the base today?

[Baroness Chapman of Darlington (Lab)]

I do not think that data is published anywhere, I am afraid. If it is, I shall provide it to the noble Lord.

I very much enjoyed the speech of the noble Lord, Lord Hannan, as I always do, but it is unjustifiable to define Chagossians as only those holding British Overseas Territories citizenship. I think that is what he was getting at. There are many Chagossians living in Mauritius, the Seychelles and beyond, and this would also exclude anyone who holds British citizenship, but not British Overseas Territories citizenship.

Amendment 20 from the noble Lord, Lord Callanan, which is one of many that would require the Government to seek something from Mauritius, is not needed. We have already committed to making a Statement to Parliament—and I think it is right that we do this—on the modalities of the Chagossian trust fund and eligibility for resettlement. That is in large part a response to the considerable interest that there has been from noble Lords across the House in making sure that the trust fund is run properly and fairly.

Taking this together with Amendment 38A from the noble Lord, Lord Hay, on air travel to Diego Garcia, I say that, as we have said numerous times, the UK is taking forward planning for a programme of heritage visits for Chagossians to the Chagos Archipelago, including Diego Garcia. These were paused in 2019 because of Covid, but we are working hard to reinstate them as soon as possible. Now, as then, these visits would include visits to key heritage sites. Specifically on the amendment from the noble Lord, Lord Hay, there are no commercial flights to Diego Garcia, and nor would they be practical, as it is a working military base that is highly sensitive. Allowing commercial flights would interfere with the operational use of the base. Heritage visits in the past have often involved the use of charter aircraft and this may be the case for future visits also, but there is nothing in the treaty that would prevent this.

On Amendment 20C, noble Lords will recall that we debated the environmental impacts of the treaty and the marine protected area around the Chagos Archipelago last week. Both the UK and Mauritius are committed to protecting the unique environment around the islands. Noble Lords will be aware that on 2 November Mauritius issued a statement announcing the creation of a marine protected area once the treaty enters into force. No commercial fishing whatever will be allowed in any part of the MPA. Low levels of artisanal fishing, compatible with nature conservation or for subsistence of the Chagossian community, would be allowed in certain limited areas.

The noble Lord’s amendment seeks to delay the implementation of the Bill and the entry into force of the treaty. The treaty has already been reviewed by two Select Committees of this House. They have reported their findings and agreed that the treaty allows for positive environmental work, with the IAC welcoming

“the Government’s assurance that it will work closely with the Mauritian Government to establish a well-resourced and patrolled Marine Protected Area”.

Amendment 38C, tabled by the noble Lord, Lord Weir, would require the Government to implement the resettlement recommendations of the 2015 KPMG study. The KPMG report, commissioned by the Conservative Government, concluded that resettling a civilian population permanently on BIOT would entail substantial and open-ended costs. The then Government ruled out resettlement, acknowledging the acute challenges and costs of developing anything equivalent to modern public services on remote and low-lying islands.

[Lord Hannan of Kingsclere (Con)]

Will the Minister confirm that there were three different options for how many people you would resettle, and the costs of all of them were substantially lower than the transfer payments that we are making to Mauritius alone under the current deal?

[Baroness Chapman of Darlington (Lab)]

That is correct, but those payments would not have paid for a legally secure operation of the base alongside our United States allies. Whatever legal geniuses we have opposite us today, those in the White House differed on the analysis now being put forward by the Conservative Party, which is clearly different from what they put forward in the not-so-distant past.

The agreement gives Mauritius the opportunity to develop a programme of resettlement on its own terms, without requiring the UK taxpayer to pick up the bill.

On Amendment 81G from the noble Lord, Lord Kempsell, as I and other Ministers have said on numerous occasions, it will be for Mauritius to establish a programme of resettlement once the treaty comes into force. I am very sympathetic to the way he put his case on this, but it would not be a good use of taxpayers’ money to keep reporting on something that is not in our gift to achieve. The Government are increasing their support to Chagossians living in the UK through new and existing projects. These include Chagossian-led community projects in Crawley and beyond, as well as education and English language support, and have involved the creation of a number of FCDO-funded full-time jobs for Chagossians. The noble Lord, Lord Ahmad, asked me about commitments on this going forward. We are committed to these at least until the end of this Parliament. He will understand that what happens beyond that may depend on decisions of Ministers in the future.

Amendment 31 tabled by the noble Lord, Lord Morrow, and Amendment 55 tabled by the noble Lord, Lord Weir, ask for an equality impact assessment on the payments to be made by Mauritius to Chagossians. The Government have already released the public sector equality duty report relating to the treaty, which addresses all the issues around equalities and the impact assessment.

Amendment 50A tabled by the noble Baroness, Lady Foster, raises a really important issue. We do not think it is necessary to make provision for this in the Bill, but we understand her concern. As I said in my letter in relation to the first day of Committee, we will work with relevant authorities to ensure that official documentation reflects historic connections to the Chagos Archipelago wherever possible. British passports issued to Chagossians will continue to display their place of birth and, if they wish, those who already have British Overseas Territories citizenship status can hold a British passport reflecting their status as British Overseas Territories citizens. I am very sympathetic to the arguments put forward by the noble Baroness and commit to making diplomatic representations to the Government of Mauritius to ensure that place of birth is recorded accurately on documentation.

[Baroness Foster of Aghadrumsee (Non-Afl)]

I very much appreciate the Minister’s commitment to do that, because this is such a hurtful thing. Sometimes, those of an Irish republican disposition will say that I am not British but just Irish, so it is something I feel very strongly about. The Chagossians are entitled to have their identity confirmed, and I would be very pleased if she could write to me after she raises those issues through the diplomatic channels.

[Baroness Chapman of Darlington (Lab)]

Of course, I would be very happy to do that.

--- Later in debate ---

[Lord Weir of Ballyholme (DUP)]

On the amendments that the noble Lord, Lord Morrow, and I put forward, as was alluded to in a number of speeches, including by the noble Baroness, Lady Foster, the reason why we raised equality issues as regards financial payments is the potential role of Chagossians within the trust fund. There is a widespread concern at present that we are simply hoping that Mauritius does the right thing with that. I appreciate that the Minister is perhaps not in the position today to give any level of direct assurances. However, can she at least go away and come back before Report with the Government’s thoughts or information—perhaps after discussions with the Mauritian Government—as to how we can inject a level of Chagossian direct involvement and control over that trust fund? That would be very helpful for whenever we reach Report.

[Baroness Chapman of Darlington (Lab)]

That is not too much to ask. We are talking to the Mauritian Government about this, because we want the same thing as the noble Lord. I had hoped that we would be able to say something a little bit more detailed about that by now. We have not quite got there, but we will use best endeavours to get there before Report. I understand the motivation behind this, and it is right that we do what we can to make sure that noble Lords have the assurances they need by Report.

[Lord Purvis of Tweed (LD)]

In light of the reaffirmation that there will be both ongoing citizenship as well as dual nationality, and, perhaps uniquely, that community will be impacted directly by the terms of this treaty, does the Minister accept the principle that formal mechanisms of representation for the duration of this agreement, rather than just between now and the treaty coming into force, in principle warrant very serious consideration?

[Baroness Chapman of Darlington (Lab)]

It depends on what we mean by formal and what that looks like. We have an arrangement at the moment via the contact group and a commitment to strengthen and expand that, to make sure that does the job it is intended to do and the Government can support it in doing that. However, we are clear that we do not do anything to it without its consent. It is an area on which we are interested in having further conversations—I think the noble Lord knows what I am getting at. Whether that completely satisfies his desire for formality, we will probably continue to explore together.

With that, I hope the noble Lord, Lord Callanan, feels able to withdraw his amendment.

[Lord Callanan (Con)]

My Lords, I agree with the Minister that this has been a fascinating debate. It was a real pleasure to hear so many noble Lords focusing, as we rightly should, on the rights and futures of the Chagossian people.

The trust fund is an essential part of the treaty. Essentially, it is the only part of the treaty that is positive for the community. Therefore, we must not allow it to be maladministered, or worse, by the Mauritian Government. My noble friend Lord Ahmad made some very good points about the management of the existing fund, to which he got some answer from the Minister. We are certainly clear that the UK Government should take all necessary steps to hold the Mauritian Government to account for their management of the fund to ensure that the Chagossians are properly looked after and no longer treated as second-class citizens. I apologise to my noble friend Lord Fuller for trying to apply a little imaginary lipstick to his proverbial pig in this matter.

The points raised by the noble Baroness, Lady Foster, were particularly important and extremely serious. I was pleased to hear the assurances given to her by the Minister. We should not allow the Chagossian people to be treated in this manner by Mauritius.

This speaks to our concerns on value for money. Whichever figures you take, this agreement is a major financial undertaking, costing the British taxpayer billions of pounds over the lifetime of the deal. Any situation where the fund is capitalised but not managed properly would surely be unacceptable, and we should make sure that there are powers to hold Mauritius to account should that happen.

My noble friend Lord Hannan, in his excellent contribution, made some great points on how the Chagossians could be resettled in future and many of the alternative occupations that they could take in such circumstances.

If the Minister is not satisfied that the Government have the powers that they need to do that, I hope Ministers will go back to the Mauritian Government to ensure that we have those stronger powers before the treaty takes effect. The Minister is right that many of these matters will be returned to on Report. In the meantime, I beg leave to withdraw my amendment.

--- Later in debate ---

[Baroness Hoey (Non-Afl)]

My Lords, I will speak to my Amendment 36, which, as the noble Lord mentioned, relates to asylum seekers who arrive on Diego Garcia, or anywhere on the Chagos Islands. Its purpose is very simple: it ensures that, if any person fleeing danger or persecution lands on those shores, they will not be subjected to unlawful detention, denial of due process, or the kinds of conditions that a British judge has already found to be in breach of international law.

I got a very nice personal letter from a native Chagossian, saying:

“We were exiled from our islands once, but we must not watch new injustice happen on our shores again. Anyone who arrives in our homeland must be treated with dignity. No one should suffer in the Chagos as we once did … As a native islander, I insist that any asylum seeker reaching the Chagos must have their rights respected. We were once denied justice. We cannot allow injustice to happen again in our name”.


Of course, the background has already been mentioned by the noble Lord, Lord Callanan—that in late 2021 more than 60 Sri Lankan Tamils were intercepted at sea and brought to Diego Garcia after their vessel was found in distress. Those individuals, many of whom intended to seek asylum in Canada, were accommodated for almost three years in a fenced compound on the island. This was not a temporary holding area; it became a long-term camp. The conditions are a matter of judicial record. The British Indian Ocean Territory Supreme Court found that the asylum seekers were effectively held in unlawful detention. The acting judge described the camp as

“a prison in all but name”

and said it was unsurprising that the individuals felt they were being punished. Evidence presented to the court documented leaking tents, rodent infestation, extreme heat, restricted movement, repeated incidents of self-harm and at least one mass suicide attempt. Some were warned that leaving the compound would expose them to the risk of being shot on security grounds. Those words are not mine—they were the court’s findings.

We also now know, again from the court’s judgment, that progress on their protection claims was impeded because of political factors, including concerns within the Home Office about the Government’s Rwanda policy. Rwanda seems to get mentioned everywhere. The effect of that delay was that these individuals were kept in a camp, in extreme conditions, for far longer than should ever have been contemplated. Most have now been brought to the United Kingdom, as has been said. I think that my noble and learned friend Lord Hermer was involved in that before he became Attorney-General. The Government described this as a one-off transfer and said that Diego Garcia would not be used again for long-term processing, but it remains the case that nothing in statute today prevents a future commissioner, Minister or Government using the islands in exactly the same way, should another vessel arrive. That is why this amendment is necessary; it gives effect to what the United Kingdom is already legally bound to do and ensures that any transfer to Mauritius or any other state happens only under an agreement that guarantees humane treatment, full rights of appeal and compliance with international law. These are not new standards; they are the minimum standards that the United Kingdom already owes to any asylum seeker, regardless of geography.

This amendment also speaks to something deeply felt by the Chagossians. The Chagossian people know what it is to be held without rights; they know what it is to have decisions made about their lives thousands of miles away; and they know what it is to be told they have no voice in decisions taken on their own islands. They have told us repeatedly that they do not want Diego Garcia, or any part of the Chagos Archipelago, to become a place where other vulnerable people suffer in silence.

There is also a simple and moral point. The only civilians permitted to remain long-term on the islands in the past decade were not the native Chagossians but asylum seekers confined in a manner that a British judge found to be unlawful. That fact alone should give the Committee pause for reflection. It was perfectly okay for asylum seekers to be on Diego Garcia but not the original Chagos people.

This amendment seeks to ensure that asylum seekers under Mauritian jurisdiction must have binding guarantees for monitoring, appeal rights, independent oversight and humanitarian standards. The Chagossian community has raised serious concerns about the treatment of vulnerable people already in Mauritius. These concerns cannot be dismissed and certainly cannot be ignored. The Government now intend that asylum seekers arriving in Chagos should be sent there.

This amendment does not oppose the transfer of asylum seekers. It does not dictate the policy of future Governments; it simply ensures that the mistakes made between 2021 and 2024 can never be repeated on British responsibility. It ensures that any person arriving on those islands is processed humanely, lawfully and with respect for their basic rights. For the Chagossians, who were themselves displaced without rights, this is not an abstract principle. It is an affirmation that the islands they still regard as home will not again be a theatre for human suffering. It is a modest and necessary amendment, which is fully consistent with our international obligations and our national values. I therefore commend it to the Committee and urge noble Lords to support it.

[Baroness Chapman of Darlington (Lab)]

My Lords, Amendments 19 and 27 from the noble Lords, Lord Callanan and Lord Lilley, now in his place, seek to ensure that Mauritius will be responsible for any illegal migrants who may arrive at Diego Garcia. These are important amendments, and it is helpful that they have been tabled to allow us to clarify this point. I can reassure both noble Lords that the treaty already ensures Mauritian responsibility and closes a potential—as they correctly identify—illegal migration route to the UK. Mauritius, as the sovereign state and as specifically referenced under Annex 2 of the treaty, has jurisdiction over irregular migration to the Chagos Archipelago, including Diego Garcia.

To the extent that the noble Lords, Lord Callanan and Lord Lilley, through their amendments are seeking clarity on the arrangements with Mauritius to put that responsibility into practice, I can assure them that the UK Government are already in the process of agreeing with Mauritius the separate arrangements referenced in Annex 2 paragraph 10 of the treaty, to assist and facilitate in that exercise of Mauritian jurisdiction. These are ongoing negotiations on which I will not provide a running commentary; suffice to say that there will be no need to force the Government to provide a report on the negotiations.

Amendment 36 from the noble Baroness, Lady Hoey, is another helpful amendment. It seeks to ensure that any arrangement entered into with Mauritius regarding migrants ensures the humane treatment, full rights of appeal and compliance with international law of any asylum seeker or refugee. It is an important amendment, and I can confirm that the Government will, of course, ensure that any arrangement we enter into will comply with applicable international law and our domestic obligations. For that reason, I think that the amendment is unnecessary, but I thank her for tabling it and allowing us to make that clear. I hope that noble Lords will not press their amendments.

[Lord Callanan (Con)]

My Lords, I am grateful to the Minister for her clarification, and to the noble Baroness, Lady Hoey, for her contribution to this important debate. We know how strongly the British public feel on illegal immigration. It would have been outrageous if we handed over the territory yet retained responsibility for dealing with any illegal immigration.

I will look carefully at the words that the Minister used in her response in Hansard, but it seems as though she has provided the reassurances we are seeking that no illegal arrivals in the Chagos Archipelago will be able to make a claim in the UK for asylum now that sovereignty has been handed over. She used the famous government expression “I am not going to provide a running commentary”, which often means “I am not going to say”. Nobody is asking her to provide a running commentary; we just wanted a clarification on the issues or any outcome of the discussions. If there is a resolution to the discussions before we get to Report, I hope she will update us in writing. Apart from that, I beg leave to withdraw my amendment.
