Diego Garcia Military Base and British Indian Ocean Territory Bill

Debate between Lord Sentamu and Lord Weir of Ballyholme

Committee stage
Tuesday 25th November 2025 Lords Chamber

[Lord Weir of Ballyholme (DUP)]

I do not hold a brief for either the Government or the main Opposition. I am happy for them to spell it out. Undoubtedly, what the noble Baroness, Lady Hoey, has said is correct, but rather than essentially being in a position where we look to see where the lines of accountability and blame should lie, we should ultimately be focusing on ensuring that we support the self-determination of the Chagossian people. That is the fatal flaw with this agreement.

[Lord Sentamu (CB)]

My Lords, I just want us to remind ourselves of the history of the British Empire and how Macmillan suddenly said: there are now winds of change and, if we resist, we may lose something very good. Her Majesty Queen Elizabeth II created this wonderful thing called the Commonwealth. She put in a lot of effort and energy, and those countries that were once ruled are now part of the Commonwealth, and what is interesting is that in most of those countries the national language is English. So there can be a transition that does not destroy a lot of goodness nor give the impression that those territories where the sovereign is still His Majesty the King will simply look at this and say, “They did it, so we can”. You will find that politically, in Jamaica and other places, the Crown has made it very clear that this is a decision of those nations. If they wanted to become independent, that is their decision. They are not going to force themselves on anybody.

I thought the treaty that was entered into with Mauritius was to create a long-term use of Diego Garcia and the archipelago. If we did not, the challenge was soon going to come because of what happened at the United Nations. We would have found ourselves with a big challenge. Even China was interested in challenging British sovereignty, but now a treaty has been signed and has secured this.

Another good thing on which I want to congratulate the Government is that they did not simply sign a treaty so that this base can be used for 99 years. Because sovereignty is now being transferred, they also provided a trust fund for the Chagossians to be better looked after than when the British had sovereignty over the place. This is a win-win situation for the Chagossians and for Britain. We now have security of the base for a 99-year lease. That is quite a long time. I do not think you and I will be here in 99 years, but those who are here may say we did a good thing at the time. As for the fear of the noble Lord, Lord Hannan, of what other places may do, it is their right to do whatever they want to do.
