Diego Garcia Military Base and British Indian Ocean Territory Bill

Simon Hoare Excerpts

Tuesday 20th January 2026 Commons Chamber

[Stephen Doughty]

I will make progress and then I will take some interventions—certainly from the hon. Member for North Dorset (Simon Hoare) and the right hon. Member for Sutton Coldfield (Sir Andrew Mitchell).

The UK will never compromise on our national security, and as we have repeatedly made clear, the agreement we struck is vital for protecting it; it guarantees the long-term future of a base that is vital for the United Kingdom and the United States and our allies, and which had been under threat. Crucially, the deal secures the operations of the joint US-UK base on Diego Garcia for generations. It has been publicly welcomed by key allies, including our Five Eyes partners, and key international partners including India, Japan and South Korea.

[Simon Hoare (North Dorset) (Con)]

Throughout the passage of this Bill, the Minister has prayed in aid the support of the United States of America and the wider Five Eyes community. This morning the President of the United States dropped what could be described as a depth charge on that and made very clear what he thinks. What are the House and the Government to read of what the Minister says was the American position on the Bill and what it appears that its commander-in-chief is saying today?

[Stephen Doughty]

We engage with the United States—our closest defence and security partner—on a range of issues, including this one, every single day, and we continue to do so. The hon. Member asks an important question. The United States and President Trump welcomed this deal in the spring, and when we discussed in detail why the agreement was needed, the strong protections that it includes and the vital security it provides for Diego Garcia, the Administration endorsed the agreement as a “monumental achievement” following a thorough inter-agency process in the United States. The hon. Member will know how serious that is.

In May the United States Secretary of State said,

“The Trump Administration determined that this agreement secures the long-term, stable, and effective operation of the joint US-UK military facility at Diego Garcia”.

We will of course have discussions with the Administration in the coming days to remind them of the strength of this deal and how it secures the base for the United Kingdom and the United States. We will continue those discussions on many levels.

[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?

[Simon Hoare]

When I and other colleagues intervened on the Minister, we seemed to get a rather la-la land answer about the Government’s response to what the President of the United States has said. In terms, the Minister said, “I’ll go and have a word with him and put him straight.” Well, good luck with that! The Government, having prayed in aid for so long the unalloyed support of the United States, have now lost it. Is my right hon. Friend as confused as I am to see that they are pretending that the incident never happened? It is like the “Bobby in the shower” moment in “Dallas”.

[Priti Patel]

I thank my hon. Friend for his comments. The Opposition are completely against this deal, and the President of the United States has said that it is going ahead “for no reason whatsoever”. It seems to me that the Government are still on hold to the President of the United States.

[Alex Ballinger]

My hon. Friend makes a good point. This treaty has been through the interagency process in America and has support across the system. Colleagues may have mentioned the President changing his position, but the US system is much wider than that, and I do not think we should we should base our long-term strategic and security interests on Truth Social posts.

This House should reject Lords amendments 1, 5 and 6, support the Government’s sensible procedural amendment 4, and pass this Bill in a way that protects national security, rather than gambling with it.

[Simon Hoare]

On a point of order, Madam Deputy Speaker—never has a point of order been greeted with such joy from the Chair—you have rightly pointed out, as has Mr Speaker, the Lords amendments that engage Commons financial privilege. We guard that privilege jealously and exercise it with caution. How is the House supposed to exercise that financial privilege in an informed way when, despite several probes to the Minister to come up with a figure for what this deal will cost the public purse, those right hon. and hon Members attending the debate this afternoon have not been given that figure? We have had a lot of theory about how a figure had been arrived at, but no figure. How do we exercise—

[Madam Deputy Speaker (Ms Nusrat Ghani)]

Order. Mr Hoare, I am worried that the longer you speak, the longer you will disappoint other colleagues who are hoping to contribute later in the debate, and I would not want to ruin your reputation on that front. This feels like a continuation of the debate. The Minister may or may not wish to respond to that point during his closing speech, but my job is to make sure that as many Members as possible who have sat through this debate get to put their voice on the record.

I call the Liberal Democrat spokesperson.
