Diego Garcia Military Base and British Indian Ocean Territory Bill

Simon Hoare Excerpts

2nd reading
Tuesday 9th September 2025 Commons Chamber

[Luke Pollard]

As I just mentioned—the hon. Gentleman might have missed it—I will give way in a moment, but I will now make some progress.

Courts and international bodies were already making decisions that undermined our position. Others would have followed suit, taking us down a path towards making the base inoperable. This Government will not allow that to happen. There has been a wealth of misinformation on these legal points, and those who have suggested that the UK should simply ignore international law fail to recognise the true impacts of these cascading adverse rulings, which would have not only impeded our ability to control and operate the base, but would have swiftly undermined our ability to control the waters, the air and the electromagnetic spectrum on which the base relies. Such rulings would have fundamentally undermined the very capabilities that make the base so uniquely valuable to the UK and the US, our allies.

This treaty eliminates that legal threat. Under the treaty, the UK will retain all the rights and authorities necessary for full operational control of Diego Garcia. It provides for unrestricted use of the base.

[Simon Hoare (North Dorset) (Con)]

Will the Minister give way?

[Luke Pollard]

In just one moment.

The treaty provides for control over the movement of all persons and goods on the base, and for control over the electromagnetic spectrum used for communications. It ensures that nothing can be built within a buffer zone of 24 nautical miles without our say so, and it delivers an effective veto on any development in the Chagos archipelago that threatens the base—something that the previous Government failed to secure in their negotiations. It prohibits foreign security forces from establishing a presence on the outer islands.

[Luke Pollard]

I thank my hon. Friend for that. It must be quite a freeing experience, because we now know that nearly every single legacy Tory MP during the last Government—whose Ministers started the negotiations, negotiated a deal, and made statements and answered questions in this House—were not actually supporting their Front Benchers, which is what we saw, but were deeply upset with the Conservative Government. If that is their genuine position, not just their political position now, they should have raised those concerns with the Foreign Secretary at the time. They should have been clear about it, but I believe that not many of them did so, and that tells a story.

[Simon Hoare]

I welcome the hon. Gentleman to his promoted position. If he is asking the House to thank him for negotiating what we already have, I think our thanks will be a long time in coming, because the outcome of the negotiations is pretty poor as far as this country is concerned. Surely we have given away what is of most strategic importance in this space as we now have to notify the Mauritian Government any time we want to do anything there. We do not currently have to do that, and therefore the element of surprise has been lost.

[Luke Pollard]

I have a lot of time for the hon. Gentleman, but I am afraid he is incorrect about the notification criteria. There is a lot of fake news out there—which I and the Minister beside me, my hon. Friend the Member for Cardiff South and Penarth, have corrected in this House before—about the suggestion that pre-notification of action is required; it is not. As is explicitly set out in the documents, we do not need to undertake pre-notification. It is established under the criteria that post-action notification for overseas bases is normal, and that would be normal for the UK and our overseas allies that have overseas bases. It is not unusual, and he will be familiar with the fact that there is further international reporting of any military action. It is important that we go on the facts. Some people are worried about the situation that the hon. Gentleman outlined, but I can reassure him that they do not need to worry about it, because what he said is not accurate.

Diego Garcia Military Base and British Indian Ocean Territory Bill

Simon Hoare Excerpts

Consideration of Lords amendments
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.

--- Later in debate ---

[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.

--- Later in debate ---

[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.
