Diego Garcia Military Base and British Indian Ocean Territory Bill

Debate between Priti Patel and Roger Gale

2nd reading
Tuesday 9th September 2025 Commons Chamber

[Priti Patel]

I will not. As we have already heard from Conservative Members, we have rarely seen the methodology that the Government are now hiding behind used for any spending announcements. When the Minister winds up, I wonder if he will commit to presenting all future spending decisions using this methodology—or perhaps he could explain why the Government have singled out this large and embarrassing expenditure to be formulated in this way. That is down to the fact that they are covering up a colossal cost.

[Sir Roger Gale]

The point has been made over and over in this discussion that we are giving away something that we did not have to give away, and are renting it back—and the British taxpayer is paying for it. Last week, I asked the Leader of the House how much this was going to cost. She said,

“alongside legislation we publish all the necessary documents, including the costings, which we have been transparent about.”—[Official Report, 4 September 2025; Vol. 772, c. 453.]

I regard the Minister as a friend, but to say the least, his figures have been opaque. Let me ask one simple question that my right hon. Friend might know the answer to: how much is the United States contributing to this deal?

[Priti Patel]

I thank my right hon. Friend for his contribution, and for pursuing this line of question in the Chamber with other Ministers. He is absolutely correct. We know that the United States of America is not contributing to the cost of the deal. The cost is solely on the British taxpayer. [Interruption.] Operational costs of the base are different; that is not in this treaty or this Bill.

The Bill represents a series of measures, not the treaty in its entirety. The Government blocked this House from voting on the treaty during the 21-day process provided for in the Constitutional Reform and Government Act 2010. Last week, when asked at oral questions why we were not getting a vote on the costs, the then Foreign Secretary—now Deputy Prime Minister—proclaimed that there would be a vote, but the Government have not seen fit to put forward a motion. As the explanatory notes to the Bill confirm, the Bill will not authorise expenditure. That is not acceptable. We will table amendments to the Bill to hold the Deputy Prime Minister to his word and ensure that this House has a rightful say over the payments to Mauritius.

Let us be clear: unless there is a direct vote on the costs, Labour will have cheated Parliament and Britain out of having a say on the financial implications of the £35 billion that British taxpayers are being forced to pay a foreign Government. That expenditure means higher taxes for British taxpayers and less spending for British people across all constituencies around the country. Shamefully, this is all to fund tax cuts, debt reduction and new investment in not our country, but Mauritius. I will gladly give way to any Minister or Government Back Bencher who wants to explain why it is acceptable to deny Parliament a vote on this £35 billion of expenditure, and why the money should be given to a foreign Government, not invested in this country. If they need to check that with Rachel from accounts or Lord Hermer, I am sure they can do so before the end of the debate. Labour giving away British taxpayers’ money to a foreign Government to rent land that we already own is reckless and irresponsible.
