Diego Garcia Military Base and British Indian Ocean Territory Bill

Debate between Graham Stuart and Priti Patel

Tuesday 20th January 2026 Commons Chamber

[Priti Patel]

If the Government wish to U-turn and scrap the Bill, we would welcome that and support it; there is no question about that.

I turn to amendment 1. It is not just when it comes to money, which is addressed in amendment 5, that the Government’s claims lack any credibility; amendment 1, which deals with the surrender of British sovereignty, leaves us weaker and, as we have heard from my right hon. and hon. Friends, will compromise the long-term operations of the base.

We are required to give notice to the Government of Mauritius about a range of activities taking place on the base. As the hon. Member for Strangford (Jim Shannon) pointed out, Mauritius is a signatory to the Pelindaba treaty, and if that applies to Diego Garcia, it would prohibit the stationing and storage of nuclear weapons there. This is very serious. While the Prime Minister has claimed that China, Russia and Iran oppose the surrender, we know that they back it; they publicly endorse it, and they will seek to gain from this lack of sovereignty.

These points are all relevant to amendment 1, as it requires the Government to renegotiate article 11 of the treaty, so that payments cease should the use of the base for military purposes became impossible. Obviously, we hope that that scenario does not materialise, as we believe that Diego Garcia is a vital cornerstone of our national security and defence, and should remain so. However, as the treaty stands, if we stop using the base, the UK is still bound to make pretty significant payments over the 99-year lease period; it is a huge cost. Amendment 1 is therefore a vital point of contingency.

We would like the whole agreement binned, but we believe that it is reasonable and practical for the Government to accept this change. When he sums up, will the Minister explain why he is not prepared to consider the amendment, and to renegotiate parts of the treaty?

[Graham Stuart]

Does my right hon. Friend, like me, feel some sympathy for the Minister? He has rested his whole case on the support of the United States of America. The Deputy Prime Minister said that the Bill would not go ahead if the American President did not support it. We all remember the great mystery about who shot J.R., but there is no mystery about who shot the Minister’s fox—it was the President of the United States last night, and the Minister’s whole case has crumbled.

[Priti Patel]

My right hon. Friend is spot on. This is the critical moment when the Government should tear up the Bill and scrap this disaster. It should not proceed at all.
