Diego Garcia Military Base and British Indian Ocean Territory Bill

Debate between Lord Purvis of Tweed and Baroness Meyer

Committee stage
Tuesday 18th November 2025 Lords Chamber

[Baroness Meyer (Con)]

My Lords, I shall speak in support of Amendments 14 and 25. This treaty and the Bill that will enact it is bad for our country, for our security and for British taxpayers. As we have already discussed, it will leave Britain poorer, weaker and strategically exposed.

This treaty is also bad for the Chagossian people. Half a century ago, they suffered the terrible injustice of forced removal. This treaty compounds that injustice by offering no guaranteed right of return, no legally binding resettlement plan and no meaningful protection of their rights. This is truly shameful. For a Government who claim to uphold human rights, it is an extraordinary moral failure.

Dr Al Pinkerton, the Liberal Democrat spokesman, said at Third Reading in the House of Commons that

“we cannot allow the Bill to pass without ensuring that Chagossians themselves are sovereign over their citizenship, the governance of their islands and the prospect of return”.—[Official Report, Commons, 20/10/25; col. 756.]

He is right, and I am surprised that no Liberal Democrat in this House has put down any amendment in support of a referendum. To deny the Chagossians their right of self-determination and to shape the future of their homeland is unworthy of a country that champions justice, fairness and democracy. This amendment would give them a chance, but it would also give us, a nation that prides itself on a centuries-old democratic—

[Lord Purvis of Tweed (LD)]

I am grateful to the noble Baroness. I make the assumption that, in her defence, she did not read my amendment before making her statement, because the right to self-determination is there under proposed new subsection (3)(b)(ii). Can she clarify what her referendum would be? Would it include the sovereignty, the possession and the inhabitation of the military base on Diego Garcia?

[Baroness Meyer (Con)]

I presume that a referendum would actually ask the Chagossian people what they want for their future and self-determination.

[Lord Purvis of Tweed (LD)]

To clarify: it is the position of the Opposition that the referendum would also be for there to able to be inhabitants on the military base?
