Diego Garcia Military Base and British Indian Ocean Territory Bill

Debate between Priti Patel and Graeme Downie

2nd reading
Tuesday 9th September 2025 Commons Chamber

[Priti Patel (Witham) (Con)]

I beg to move an amendment, to leave out from “That” to the end of the question and add:

“this House declines to give a Second Reading to the Diego Garcia Military Base and British Indian Ocean Territory Bill because it implacably opposes the United Kingdom ceding sovereignty over the British Indian Ocean Territory to Mauritius, and is therefore opposed to the terms of the Treaty to which the Bill gives effect, in particular Article 11 of the Treaty which will mean the United Kingdom paying £34.7 billion to Mauritius, leading to tax rises in the United Kingdom to provide tax cuts in Mauritius; because the Treaty does not secure the base on Diego Garcia, in particular because it does not embody the “right to extend” the 99-year lease to which the then Secretary of State for Foreign, Commonwealth and Development Affairs referred in this House on 7 October 2024; because the measures in the Treaty leave the base vulnerable, and therefore represent a threat to the strategic interests of the United Kingdom; and because the Treaty does not properly protect the rights of the Chagossian people, or the future of the Marine Protected Area.”

We on the Opposition side of the House stand against Labour’s £35 billion Chagos surrender deal. Everything about this surrender deal is wrong, from the way it was negotiated behind closed doors within weeks of Labour coming to power, to the betrayal—[Interruption.] I will happily give way.

[Graeme Downie]

The right hon. Lady says “behind closed doors”. Will she please publish the previous Government’s negotiating position, including the cost of the deal they were looking to do?

[Priti Patel]

Let me be clear: I was not a member of the previous Government, but the hon. Member knows perfectly well that no one on the Conservative Benches has any authority to publish classified papers from previous Governments. [Interruption.] He might laugh about that, but those on the Labour Benches might want to apologise to Lord Cameron of Chipping Norton, who actually stopped the deal. He has been grossly misrepresented this afternoon in this debate.

My hon. Friend is absolutely right; at the heart of this is transparency about negotiations, including fiscal negotiations.

[Graeme Downie]

The right hon. Lady talks about transparency, but once again we have not heard a word from her about what her Government’s position would have been, so there has been no transparency at all. They went through 11 rounds of negotiations. If she did not believe a deal was possible, surely she would have stopped after two or three. She knew that a deal was vital to UK security interests, but her Government could not conclude it.

[Priti Patel]

The hon. Member, who was laughing and sneering at fellow colleagues earlier—that is simply not acceptable—should have listened to what I said. I will restate it for the House: there was no deal done whatsoever.
