Diego Garcia Military Base and British Indian Ocean Territory Bill

Peter Lamb Excerpts

2nd reading
Tuesday 9th September 2025 Commons Chamber

[Peter Lamb (Crawley) (Lab)]

I congratulate the Minister on his appointment, and thank Ministers for the time they have given me to raise with them matters in relation to this Bill and for the responses they have provided to my questions.

I can see no logical reason why the Government would go through the painful process of bringing this Bill to the Floor of the House today if they were not 100% convinced that it was in the UK’s national security interests. However, I am afraid that I must vote against the Government today because I do not believe that their concerns, no matter how important they might be, give us the right to override the Chagossian people’s right to self-determination. We cannot vote to give away these islands, because they are not our islands to give away in the first place.

I know that many Members have taken an interest in the plight of the Chagossian people over the years, and that in the last year, hopefully, many more have learned more about their history and their circumstances, so I will recount the key points briefly. The first recorded contact with the islands was from those in the Maldives, but its modern history begins with France, which bound the islands together in a colonial administration with Mauritius. This is the only basis on which the modern state of Mauritius makes any claim on the islands.

In the late 18th century, the UK claimed the colonies from the French and planted coconut plantations on the islands. We used slave labour to do that, and it was among those slaves that the unique island culture began to develop. In 1965, the UK divided that colonial entity, granting the modern state of Mauritius independence and at the same time, in return for financial compensation, agreeing to give up any future claim on the islands. However, we had already come to the determination at that point that this would be a convenient location for a military base, jointly run with the United States. I believe that in that initial deal we got a discount on Polaris for providing the site.

In order to facilitate the base, the decision was taken to forcibly remove the islanders from the archipelago—something that began under a Labour Government but concluded under a Conservative Government. Official documentation from the time stated that the base was too important to the UK for “Tarzans” and “Man Fridays” to get in the way, and made it clear that the islanders must be referred to only as Mauritians or Seychellois, recognising the opposition that they would face—even in the 1960s—if it was known that the displacement of an entire people was taking place in the interests of national security.

The islanders were deposited on Mauritius and the Seychelles—islands of a different culture—without a penny to their name, and for decades were abandoned by the British Government, left in poverty and facing discrimination on the basis of their ethnicity. For years, they have fought for their rights, and they have won some concessions in that time, including the right to UK citizenship, with most British Chagossians choosing to set up their home in Crawley. That move came with enormous challenges—a point to which I will circle back in due course.

I have known and worked alongside members of the British Chagossian community for almost two decades. As council leader, I promised them that as a part of Crawley’s community, it was my job to be their voice to Government, not the other way around. It is that promise that leads me to vote against this deal today.

It is true to say that there are Chagossians who enthusiastically support the deal, just as there are those who desperately oppose it—that is the same with any community on absolutely any issue—but what is not disputed is that the islands belong to the Chagossians, and that it is for that people and that people alone to decide the future of their homeland. We have not given them that chance to decide their future. Until every Chagossian has had the chance to have their say, I cannot support this deal.

[Dr Evans]

The hon. Member is making a powerful point. We heard an impassioned defence not to bring the Falkland Islands or other British overseas territories into this, but Gibraltar and the Falkland Islands have self-determination, voted for by their people. Is it his thesis that that will apply for the Chagossians, and therefore they would make the determination whether to be British or, indeed, go to the Mauritians on that basis?

[Peter Lamb]

It is incredibly unfortunate that the Chagossians have not been given that opportunity—that is my view. Had we given them that opportunity, whatever the outcome, I would have had no problem honouring that because we are talking about their land; it is not our land.

[Jeremy Corbyn]

The hon. Member is speaking very well on behalf of his constituents. He will acknowledge that the argument for Chagossians having a right of nationality and abode in Britain was hard fought by many of the Chagossians, and some of us who were here at the time were pleased to support them in that. Yes, there are differences of opinion among Chagossians, including the Chagos refugee association, which, broadly speaking, supports this treaty, but does he not think that it is time to bring all the communities together and recognise that they have achieved an enormous amount in gaining the right of return and the right of residence, at least on the archipelago?

[Peter Lamb]

There is an enormous challenge, as I am sure the right hon. Member is aware of from his many years working with the group, in the number of disparate voices. Crawley borough council had taken it on itself to work with the different community groups, helping them to come together and form a coherent voice, out of the belief that they will only ever secure what they are all seeking by having one coherent, democratic voice for the community. Unfortunately, the deal emerged during the course of that process so there has not been that opportunity, and its timing has, to an extent, driven a rift through that community.

I am not naive; I am certain that the Bill will proceed today, so let me turn to the question, “What next?” Although mention of the Chagossians is made in the wording of the deal, I remain concerned, as other Members have alluded to, that there are gaps that leave the Chagossian people at risk. While there is the option for Chagossians to be allowed by the Mauritian Government to return to the islands, there is no requirement in the deal that that happens. There is no guarantee that any Chagossian who does return to the archipelago will not face restrictions that prevent permanent habitation, even at a subsistence level of economic activity. There is no guarantee at this time that the trust fund that is being created will be in the control of the Chagossians and used exclusively to address the consequences of their forcible removal from the islands. There is no guarantee that returning Chagossians will not face a 10-year prison sentence for questioning Mauritian territorial integrity through taking on British citizenship.

I know that many remain upset that Diego Garcia remains off limits for permanent habitation, with a view that some creativity could be used to enable rehabilitation without affecting security, particularly given the prolonged period in which asylum seekers have been present on that island. I say all this because I want to urge Ministers to continue to engage on these matters with the Mauritian Government to give the Chagossians certainty over their place in this deal.

Closer to home, there are many challenges facing Chagossians who choose to exercise their right to UK citizenship. Chief among those problems, as with so many other issues, is housing. As part of our national housing strategy, we need to ensure that every UK citizen has access to good-quality housing, and that includes British Chagossians, who, by the legal complication of their citizenship, despite having lost their homes in Chagos, receive none of the support offered by relocation schemes to other groups. That creates enormous pressures on local authorities near airports and leaves many Chagossians living in dilapidated housing conditions, if they can find accommodation at all. With the second worst housing crisis in the country, the reality is that Crawley borough council cannot on its own owe the entire country’s housing duty to the Chagossian people; a national strategy is needed.

There are challenges around access to language training and support services, which often lead Chagossians to be highly reliant on other members of the community. I regret to say that for the enormous amounts of goodwill and charity on the part of that community towards other members of it, we have had instances of that trust being abused in the form of fraud. We need a mechanism for qualifications issued in Mauritius to be recognised in the UK, and for children and young people to transition into UK educational systems—something that is complicated by the differences in term times.

Lastly, there is a desperate need for facilities for the Chagossians to preserve their unique, intangible cultural heritage, which sits at the heart of an individual’s identity and which forced deportations have to a large extent erased. With so few first-generation Chagossians left, if we do not act now, this is likely to be the last generation that sees its culture on the earth. I know that Foreign Office Ministers are meeting with Chagossian groups and have been working to get funding moving again. I am hopeful that these meetings will continue and that progress can be made on these and other challenges.

I say to all Members in the House today that this House has done enormous harm to the Chagossian people, all the way from their enslavement to the present day. I believe that handing these islands to Mauritius without their consent risks making some of that harm permanent. Nevertheless, it is within the Government’s power to address many of the consequences of forcible deportation so long ago. Regardless of the outcome of today’s vote, I beg Ministers to let this be the start and not the end of the process of making things right.
