Diego Garcia Military Base and British Indian Ocean Territory Bill

Debate between Priti Patel and Esther McVey

Consideration of Lords amendments
Tuesday 20th January 2026 Commons Chamber

[Priti Patel (Witham) (Con)]

Labour’s Chagos surrender Bill is back, and this House has its last chance to act in the national interest, defend the rights of the Chagossian community and protect the money of hard-pressed British taxpayers, who are being expected to foot a colossal bill of £35 billion, which is being given to a foreign Government to—guess what?—cut their taxes, while our taxes rise.

I put on record the thanks of Conservative Members to the other place for their scrutiny, and their diligence in once again holding this Government to account. When Labour plotted to deny this House a debate and a vote on the surrender treaty during the 21-day process under the Constitutional Reform and Governance Act 2010, it was Conservatives in the House of Lords who forced a debate and a vote. When Labour limited the time for this House to give the Bill the line-by-line scrutiny it needed, it was the House of Lords that stepped in and made time available. When this Labour Government ignored and neglected the views of the Chagossian community, it was the House of Lords and the International Relations and Defence Committee that came to the rescue and organised a survey, giving important insights into Chagossians’ concerns about the Government of Mauritius and the future of their ancestral home. When Labour refused to accept any amendments to modify and improve this £35 billion surrender Bill, it was the House of Lords that made important changes, which we are debating today.

Let me be clear: this is a Bill that the Conservatives have fought against at every single stage. We will not accept this deal to surrender British sovereignty; it is a deal that we will continue to oppose and challenge Ministers on. Every vote today is a vote to kill this Bill. We will keep on voting against this Bill and opposing it until the Government—and, one would hope, the Prime Minister—see sense, withdraw it and tear up the treaty. We are not the only ones vociferously opposing this, because we now know that the President of the United States is against it; he says that it is being done “for no reason whatsoever”, and that China and Russia will

“have noticed this act of total weakness.”

[Esther McVey]

I asked the Minister what the reasons were for the Government signing away the Chagos islands. He could not give any reasons. The President of the United States says that the Government are giving the islands away “for no reason whatsoever”, so can my right hon. Friend give us any reason to sign off this deal today?

[Priti Patel]

Let me remind my right hon. Friend exactly what the President of the United States said. He has said that this is being done “for no reason whatsoever”, and that

“There is no doubt that China and Russia have noticed this act of total weakness.”

The previous Foreign Secretary, now the Deputy Prime Minister, is on the record as saying:

“If President Trump doesn’t like the deal, the deal will not go forward… they’ve got to be happy with the deal or there is no deal”,

so why has Labour continued to press this Bill?

In the light of the President’s comments, can the Minister tell us what will happen to the status of the 1966 exchange of notes between the UK and the United States, which states clearly that the British Indian Ocean Territory

“shall remain under United Kingdom sovereignty”?

What is the impact on that agreement? Is it being changed?
