Diego Garcia Military Base and British Indian Ocean Territory Bill

Debate between Graham Stuart and Danny Kruger

Committee of the whole House
Monday 20th October 2025 Commons Chamber

[Danny Kruger]

I am grateful to the Minister. I suspect there has been a private conversation with the American Government as well, and that in recognition of the fait accompli that this Government have yielded to Mauritius, the Americans have extended this somewhat limited statement of support for the deal as some kind of favour to the Prime Minister, in exchange for support he has given them on other matters. The fact is that this deal is bad for Britain and bad for Britain’s sovereignty, and behind the scenes we know that the Americans do not support it.

I want to talk about secret deals, because my only addition to the debate—very powerful points have been made already—is to say that secret deals have been done with respect to the Chagos islands in the past. Under the 30-year rule, archival evidence has come out recently of a secret deal with respect to the base at Diego Garcia between the British Government of the day—the Thatcher Government—and the American Administration. That deal was done in the national interest. The renewal of the nuclear deterrent—the Trident programme—was being set up, and there was an agreement with the Americans whereby they could expand their access and the use of Diego Garcia in exchange for a reduction in the fee, essentially, that the British Government were charged for collaboration on the Trident programme. We had to pay significantly less than we would have paid otherwise because of the expanded access that we were giving to the Americans in those years. It was called the Diego-Trident package in the negotiations and the correspondence between the British and the Americans at that time. It was kept quiet for understandable reasons, and we only know about it now. I worry that there is a similar lack of transparency around this deal because, as I say, it cannot possibly be a deal that is in the national interest.

[Graham Stuart]

We are trying to get to the bottom of precisely why the Labour Government would make this deal. The hundreds of people who worked at the Vivergo plant in my constituency were sold out by the Prime Minister who, in a personal call with the President of the United States, surrendered the entire bioethanol market of this country to the United States, with nothing in return, at the end of an already concluded trade deal negotiation. It is things like that that make us worry what is behind this Bill, what is the secret deal and exactly who has been sold out.

[Danny Kruger]

The right hon. Gentleman is absolutely right. The key demand that this House is making is for greater transparency about what is going on behind the scenes with this deal. I implore the House to insist that, before Parliament accepts any new arrangements for the sovereignty of the Chagos islands, Ministers explain what is going on. Specifically, is the Minister aware of any effect on our nuclear posture? Is there any relationship between the deal that is being done today and implications for our deterrent? The base is vital to our national interest, and I would be grateful to understand whether any discussions have been had with reference to the deals that were done many years ago about the relationship with the nuclear deterrent.
