Diego Garcia Military Base and British Indian Ocean Territory Bill

Scott Arthur Excerpts

Monday 13th April 2026 Commons Chamber

[Stephen Doughty]

I will start by thanking the right hon. Lady, who has rightly scrutinised many different aspects of this matter over many months. I have come dutifully to answer many questions, I have met with her privately, and the subject has been scrutinised by many Committees. It was right to update the House today on these developments, and I am glad that she acknowledges that point.

Of course, it is not for the Government simply to choose easy paths. It is for the Government to choose the right path: the path that is in the interests of Britain and our national security, and that of our allies. At the heart of this is a fundamental question. The Opposition know that there is a huge challenge. They knew that there was a problem, which is why they started the process. Throughout all the exchanges we have had, they have never been able to answer that simple question.

I cannot recall a time when we have seen so much misinformation and, quite frankly, negligent disregard for the national interests and security of the British people. It is regrettable that the official Opposition and indeed the Reform party—I see that only one of its Members has turned up today—have been at the heart of this. Of course, they will say that this is just politics and that the Government should be thick-skinned, but quite frankly the British public deserve better.

The national interest is what drives this Government and our national security, as the Conservatives well knew, which is why they started the process. We have seen frankly ludicrous disinformation about the operations of the base, about the genuine threats that it faced, and about the security provisions in the treaty, which of course we strengthened. We also seen it about the costs: no matter how often they give false figures, that does not make them any more accurate. We have also seen it about the views of Chagossians—I accept that they are wide and varied but, conveniently, the Opposition always ignore the views of the significant numbers of Chagossian communities and groups who feel very differently about the treaty and have supported it since the start. Indeed, we have seen it about the protection of the environment.

The Opposition operate in a state of convenient amnesia, but they know the reality, they knew the jeopardy facing the base and they know that they presided over 11 rounds of negotiations. They published it in ministerial statements and in records of meetings with the Mauritian Prime Minister. They know, too, that the treaty signed by this Government was born of their policy choices and their negotiation mandates. As ever, the Opposition cannot run away fast enough from their record in government when it suits their tiresome politicking. The British people are not fooled. They can see the hypocrisy, and they deserve better.

[Dr Scott Arthur (Edinburgh South West) (Lab)]

I thank the Minister for working over many months with our allies on this issue to reach agreement in our national interest and theirs. He has remained consistent on this issue and has given many updates on it. I wish I could say the same about the Opposition. Their short memory, their flip-flopping and their complete disregard for national security are very similar to the position they have got themselves in with Iran—very, very similar. They are laughing in the face of real threats to our national security.

I am actually quite concerned, because it seems to me that the status quo is not in our national interest. What does being without a treaty mean for the long-term access to the base, for us and for our allies?

[Stephen Doughty]

My hon. Friend sets out the fundamental issue: the risks to the operation of the base, which the Opposition knew all along. That is why they started the process, to which we have responded with this treaty, which protects our security and that of our allies. I will not speculate about the coming of those risks, but we know that we need to put things on a secure footing. We know that the treaty was the best way to do that. We know that this was agreed under two Administrations across the United States in an inter-agency process. We continue to believe that it is the right way forward, and we will announce our business in the usual way.
