Speaking in the House of Lords on 18 November 2025

Debate

Diego Garcia Military Base and British Indian Ocean Territory Bill

Contribution

I thank noble Lords for their comments on this. I feel that we have discussed the issue of a referendum fairly comprehensively, as the noble Baroness suggested. The noble Lord, Lord Lilley, pointed the finger at the Lib Dems and accused them of inconsistency. I do not always see eye to eye with the noble Lord, Lord Purvis, nor with the Liberal Democrats, but if you want consistency on this issue, I do not think you could do much better than the noble Lord or his colleague, the noble Baroness, Lady Ludford, who has championed the rights of the Chagossians for very many years. I have frankly never heard a peep out of the noble Lord opposite or from many of his colleagues on this topic, the rights of Chagossians, resettlement or anything else to do with the Chagos Islands. If we are after consistency, then the Liberal Democrats have, to be fair, been pretty consistent on this issue for very many years now. On the issue of a referendum, I remind the Committee that negotiations on the treaty were between the UK and Mauritius, with our priority being to secure the full operation of the base on Diego Garcia. The Chagos Archipelago has no permanent population nor has ever been self-governing. No question of self-determination for its population can therefore arise. This has been tested in the English courts, as we said in our earlier debate, in a series of judgments since the 1970s. The transfer of sovereignty does not deprive the Chagossians of any existing right. A time for a referendum or some formal legal basis of a consultation would have been prior to this point, maybe even prior to or during some of the 11 rounds of negotiation undertaken by the previous Government. This is despite the fact that they clearly now think that there is absolutely no legal risk to the security of the islands. It is really important that we do not allow the Chagossian community to have the impression that a consultation or a referendum held now would in any way be able to affect a treaty that has already been agreed by two Governments and that we have been instructed to ratify by votes in both Houses. The Bill has also been through all its processes in the other place. With that, I hope the noble Lord decides to withdraw his amendment.
