Diego Garcia Military Base and British Indian Ocean Territory Bill

Ben Obese-Jecty Excerpts

Tuesday 20th January 2026 Commons Chamber

[Stephen Doughty]

With the greatest of respect to the right hon. Lady, I do not think she has been present in many of the other debates on this issue—she popped up here today to make these points. I have been clear and answered the question already, so I will not do so again.

[Ben Obese-Jecty (Huntingdon) (Con)]

I thank the Minister for giving way and for his detailed explanation of how the calculations have been made. The Government Actuary’s Department clearly stated that this deal would cost £34.7 billion. That figure was then confirmed by his colleague, the Minister for the Middle East, who said that all the figures had been ratified by the Government Actuary’s Department, but his colleague sitting next to him, the Minister for Defence Readiness and Industry, told me that that figure was inaccurate. Will the Minister therefore clarify how much this deal costs?

[Stephen Doughty]

We set out the costs clearly at the time, as I have done for the hon. Gentleman in the Chamber a number of times. What I will confirm is that they have been verified by the Government Actuary’s Department. The House of Commons Library has been through them and reached the same conclusion. The Office for Statistics Regulation has welcomed the Government’s approach and said that it is in line with intelligent transparency, and the Office for Budget Responsibility also confirmed separately to it that the discount rates were correct. I have given the hon. Gentleman four good reasons and the costs. However much Opposition Members bandy about the costs, it is simply unhelpful.

I will move on to the other amendments. Lords amendment 6 would introduce an ongoing estimates and supply scrutiny process for expenditure under the treaty, including parliamentary approval for future payments and supplementary estimates. The agreement has undergone intense scrutiny, and the treaty provides robust mechanisms for dispute resolution under article 14. It is normal practice for payments under treaties to be made under the prerogative power and charged on the Consolidated Fund under the authority of the Supply Acts. Furthermore, the amendment would infringe on the financial privilege of the Commons and affect the Commons’ arrangements for authorising expenditure. These are long-standing practices that members of the former Government will know. The same applied under them, and it applies under this Government, too.

Finally, subsection (4) would infringe on the prerogative power to make and unmake treaties. It is not wise to impose any immovable requirements about a hypothetical set of circumstances that might arise in the future. This provision risks requiring the Government to breach the UK’s obligations under a treaty. It is clearly preferable for all options to be open to a future Government, so that they can deal with whatever the future may bring and act in the UK’s best interests, taking into account all the circumstances.

I am conscious of your exhortations about time, Madam Deputy Speaker, and I know that a number of right hon. and hon. Members wish to speak. The previous Government recognised that there was a problem. They engaged in 11 rounds of negotiations, but failed to reach a deal that was in our interests and those of the United States. We secured this deal. It protects the base, and the interests of the United States and our Five Eyes partners.
