Diego Garcia Military Base and British Indian Ocean Territory Bill

Mark Francois Excerpts

2nd reading
Tuesday 9th September 2025 Commons Chamber

[Sir Jeremy Wright]

If the hon. Gentleman is patient, I promise that I will come to that, but I wish to deal in a logical order with what Ministers have themselves said to justify their actions.

On 5 February, the Minister of State at the Foreign Office answered another urgent question. In answer to my plea to give us more clarity on exactly what legal basis the Government were acting on, he said:

“We currently have unrestricted and sole access to the electromagnetic spectrum, which is used to communicate with satellites and which is guaranteed and governed by the International Telecommunication Union, a United Nations body based in Geneva. If we lose it we can still communicate, but so can others.”—[Official Report, 5 February 2025; Vol. 761, c. 760.]

I understand the point that he was making, but he did not explain how that issue might lead to a binding court ruling against the UK, and he did not even take a second opportunity to do so when asked about it again by my hon. Friend the Member for Spelthorne (Lincoln Jopp)—those interested can find that answer in column 762.

Luckily, however, my right hon. Friend the shadow Foreign Secretary called a debate on this subject in Opposition time on 26 February, which was answered by the then Minister of State, the right hon. Member for Oxford East (Anneliese Dodds).

She repeated:

“Without a negotiated solution with Mauritius, it would pursue its legal campaign…That would lead to an inevitable, legally binding judgment,”.

She was then interrupted, but went on to say that

“in that kind of situation”—

presumably that is the delivery of a binding judgment against the UK—

“we would unfortunately see international organisations following that determination, such as the International Telecommunication Union.” —[Official Report, 26 February 2025; Vol. 762, c. 874.]

If we put all those ministerial utterances together, we are going round in circles.

The Government say that they have to act because of the inevitability of a binding court judgment against the UK. They mention the ICJ, but the ICJ cannot make a binding judgment against the UK on this. They hint at ITLOS cases, but those refer to ICJ decisions. The Government then say that they are worried about the actions of the International Telecommunication Union, but when pressed that seems to mean actions that would follow a binding court judgment. We are back to square one.

[Mr Mark Francois (Rayleigh and Wickford) (Con)]

Is it the case—my right hon. and learned Friend is a former Attorney General—that the ITU treaty to which we and others are a party states specifically that the ITU has no authority over the allocation of military spectrum, or military communications? It is clear that the ITU has no leverage legally at all over Diego Garcia.

[Sir Jeremy Wright]

My right hon. Friend makes an important point, which I know he has made before. I repeat the point I made earlier: we are simply not getting from the Government an adequate rebuttal of these points, and we need to have that. If the Government have a good answer to what he and my hon. Friend the Member for Hinckley and Bosworth (Dr Evans) have said, Second Reading of the Bill is the moment for the Government to deliver that explanation. We are all still waiting.

[Sir Jeremy Wright]

I am extremely grateful to my right hon. Friend, and perhaps I should refine my argument. It is not just that the Government are not answering the questions; it is that when they do answer the questions, they undermine their own argument. It is worse than we thought. We are not getting clarity from the Government about what would be the legal judgment that they themselves have relied on as almost the entire basis for their actions, and this really matters. The Government owe us a proper explanation.

I am prepared to concede—I hope the Minister will accept that I am a fair-minded person—that there may be a persuasive argument that the Government could make about which court and which circumstances would deliver the kind of judgment that makes this action inevitable and necessary, but I have waited a long time to hear it, and I am still waiting. I hope that when the Minister stands to sum up the debate he will give us that answer, because the House of Commons deserves to hear it.

[Mr Francois]

This is fundamental to the whole argument. We have pressed the Government for months to tell us what the legal threat to the islands was. In his opening speech the Minister said that it was UNCLOS. That was the justification they have given us. Does my right hon. and learned Friend agree that we have a general opt-out and two specific opt-outs under article 298(1)(b) of the United Nations convention on the law of the sea, which includes “disputes concerning military activities”? We have an opt-out from UNCLOS. The Government’s whole case is spurious—£35 billion worth of spurious.

[Sir Jeremy Wright]

It is certainly very expensive. I know lawyers who charge big fees, but none of them would come close to that.

My right hon. Friend makes his point, and again, the Minister will have another opportunity when he speaks. It is not good enough, I am afraid, for hints and oblique references to be made. We are owed a clear explanation. This is a fundamental decision on defence and security, and in financial terms as my right hon. Friend has just said, and we deserve to know. If the Minister tells the House that describing all that in detail is the sort of confidential and sensitive information that the whole House cannot hear, I have good news for him: that is what the Intelligence and Security Committee of Parliament is for. I have the honour to be a member of that Committee, and it is perhaps regrettable that the Government did not choose to explain themselves and make their case to us before they brought the Bill to the House, but they did not.
