Diego Garcia Military Base and British Indian Ocean Territory Bill

Lord Kerr of Kinlochard Excerpts

2nd reading
Tuesday 4th November 2025 Lords Chamber

[Lord Kerr of Kinlochard (CB)]

My Lords, over breakfast I read the views of the noble Lord, Lord Biggar, and can confirm that they have not changed over the course of the day.

I begin with an apology to the noble Lord, Lord Lilley. He, the noble Lord, Lord Jay, and I spent 10 years in the Permanent Secretary’s office in the Foreign Office, and I certainly never discovered the secret plan to cede sovereignty over the Chagos Archipelago that officials were apparently sitting on. I saw a number of changes of Foreign Secretary, and I cannot remember ever seeing the huddle of officials saying, “Is this the soft one we can manage to persuade that it’s time to cede the Chagos Archipelago?” I believe that the noble Lord, Lord Lilley, may have been watching too much “Yes, Minister”. It is sad that he has never been Foreign Secretary, because he has far too high an opinion of officials in the Foreign Office.

I have only three small points to make; I will be very brief, because I spoke at enormous length when we debated the treaty in July. At that time, the Opposition suggested that the treaty should not be ratified, but the House voted that it should be ratified. It cannot be ratified without this Bill; therefore, we should now pass it. That is my first point.

My second point is about the China syndrome. We heard then, and we are hearing again today, even from the Opposition Front Bench, the theory that recognising Mauritian sovereignty somehow opens the door to Chinese influence in the Chagos Archipelago and to a Chinese threat to the base. I have never understood this theory. If the risk were real, why did the Indians warmly welcome the treaty? Why did Secretary of State Rubio in Washington call the treaty a “monumental achievement”? Mr Rubio, like President Trump, is hardly soft on China. Mauritius is one of the only two African countries that have not signed up to the belt and road initiative. Why would the Mauritians enrage the Indians, to whom they are close, by helping the Chinese, whom they seriously distrust? Why would they forgo the payments we would be making? The theory makes no sense, and I strongly suspect that some of those who advance it know that perfectly well.

That brings me to my third point, which is, of course, the emollient one. The pernicious doctrine that the duty of opposition is to oppose, regardless of principle, merit or consistency, is perhaps particularly irresponsible in the sphere of foreign affairs. Mr Cleverly announced in 2022 that we would open negotiations to

“ensure the continued effective operation of the joint UK/US military base on Diego Garcia, which plays a vital role in regional and global security”.—[Official Report, Commons, 3/11/22; col. 27WS.]

We agreed; I heard no dissent. I did not know about the approaches of the noble Lord, Lord Murray. There was no public dissent from what the Government were going to do.

Under Foreign Secretary Cameron, negotiations continued—11 rounds, as the noble Baroness, Lady Chapman, reminded us. I am rather sorry that the noble Lord, Lord Cameron, is not here tonight. It would have been very good to have his verdict on the Bill which results from the work he supervised. The legal issues and the China risk explored by Conservative Back-Benchers today will have been thoroughly explained to him at the time. Indeed, we now know that the noble Lord, Lord Murray of Blidworth, no less, advised against the course that he was pursuing. There is nothing new in these arguments. They were known to the Conservative Ministers who proceeded with the negotiations.

The noble Lord, Lord Blencathra, said that it is one thing to start a negotiation about transferring sovereignty and quite another to conclude one. That is very true, but if I were absolutely determined not to cede sovereignty, I do not think I would start a negotiation about ceding sovereignty. I do not think, if I was strongly convinced that it was a bad idea, that I would have let it run on for 11 negotiating rounds.

We are shortly to hear from the Front Benches. I look forward to hearing from the Liberal Democrats; their concerns about the Chagossians do them credit. Their reservations about the treaty are ones I understand —they are honourable, although I believe they are unjustified.

We will also be hearing from the Conservative Front Bench—the heirs of Cameron and Cleverly. I have the greatest respect for the noble Baroness, Lady Goldie, not least because she hails from my part of the world. So my hopes are high that, unlike some of her colleagues, including those on the Front Bench, she will contrive to steer clear of the twin rocks of hypocrisy and irresponsibility.

--- Later in debate ---

[Baroness Goldie (Con)]

My Lords, I will try to get this debate back on track and deal with the issues that I think have been confronting us. The debate was ably introduced by the Minister and it has been predictably interesting, presenting some sharply contrasting views. It has also demonstrated a dichotomy between sincerely held views of former and venerable public servants and political views. There has been a further dichotomy within the political classes as to what constitutes responsible decision-making. As my noble friend Lord Murray indicated, even within the same party you can sometimes find a dichotomy of view—it happens, I say to the Minister. I have to say to the noble Lord, Lord Purvis, that when it comes to a party having differences of view, I would think the Liberal Democrats could give master classes.

The position of these Benches was laid out clearly by my noble friend Lord Callanan. He also addressed the precipitate and surprising decision of the Government to delay their own Bill by, unusually, not proceeding with a committal Motion. The Minister, with admirable verbal gymnastics, sought heroically, if perhaps not completely convincingly, to explain that decision, but I think the reason is simple: the Government had concerns that the sensible amendment to the committal Motion that my noble friend had tabled was drawing support, and it may well have been that the Government were fearful that support for the amendment or a version of it would prevail and the Government would lose. But that was a judgment for the Government to make. I observe that the amendment was not prescriptive and would have left matters entirely under the control of the Government. What has now emerged is a welcome breathing space for the Government to consider and answer some serious questions about the agreement on which the Bill is predicated. Some of these questions have already been asked, but it will be my pleasure in a moment to add to them.

My noble friend Lord Callanan raised some of the most serious issues arising from the agreement, and it is interesting that the concerns he expressed were mirrored during the debate by a number of contributors. If we look at the agreement and at the trust fund, we find that there is an absence of knowing in detail what the views of the Chagossian people are on these issues. That was raised by a number of contributors, including my noble friend Lord Lilley, and the noble Baroness, Lady Ludford, has concerns about that.

The noble Lord, Lord Morrow, and my noble friends Lord De Mauley and Lord Bellingham spoke movingly about the treatment to which the Chagossian people have been subjected over decades. I found that moving— I say to the noble Lord, Lord Kerr, that I am not being hypocritical in expressing that sentiment—and it was very much echoed by the noble Baronesses, Lady Hoey and Lady Foster of Aghadrumsee, who graphically described the lack of engagement in relation to current matters.

Then there is the issue of money—in today’s economic climate, a hot potato if ever there was one. The Chancellor is scratching around looking for every penny she can find, defence urgently needs upfront cash and taxes are almost certainly going up, yet the British taxpayer is going to be asked to pay almost £35 billion to Mauritius, a point that was raised by a number of contributors. My noble friend Lady Noakes gave a devastatingly forensic analysis of the costs and the Government’s disparate approach, and I will leave that to the Minister to respond to. Those concerns were echoed by the noble Baroness, Lady Foster of Aghadrumsee, and the noble Lord, Lord Weir of Ballyholme.

Then there was the position of China, and the not imagined but avowed objective of China to strengthen ties with Mauritius because of its strategic advantages, and China’s commitment to elevating the bilateral strategic partnership. These clearly cause concern to many of your Lordships, notably my noble friend Lord De Mauley. Even the noble Lord, Lord Beamish, nobly supporting his Government, said, “China is a threat”. I agree. That was again referred to by the noble Lord, Lord Weir of Ballyholme. I say to the noble Lord, Lord Kerr, that I was a Defence Minister for nearly four and a half years, and one of my areas of responsibility was south-east Asia. China is a resolute prosecutor of its own interests, with an overt desire to exercise influence globally. At our peril do we waver in our vigilance.

[Lord Kerr of Kinlochard (CB)]

I am so grateful to the noble Baroness. I just want to say that I am quite sure that the Mauritians would agree with that.
