Diego Garcia Military Base and British Indian Ocean Territory Bill

Debate between Luke Evans and Peter Lamb

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.
