I welcome the opportunity to make clear my opposition to any proposal to give away this strategically important sovereign British territory. This is not merely a territorial concession; it is an act of strategic self-sabotage, a dereliction of duty and an unforgivable betrayal of our national security. At a time of growing global instability, when our adversaries are watching for any sign of weakness, Labour has chosen to send precisely the wrong signal: that Britain can be pressured into abandoning its own territory.

This decision is indefensible on every level. The Chagos islands, and specifically Diego Garcia, have been a vital strategic asset for the UK and our allies for decades. The military base on Diego Garcia has played a crucial role in global security operations, supporting counter-terrorism efforts, maritime security and regional stability. It has been instrumental in projecting western power in the Indo-Pacific, a region increasingly shaped by geopolitical competition, particularly with China. By ceding sovereignty over these islands, Labour has put at risk Britain’s strategic interests and undermined our ability to operate in the region. What makes this decision even more staggering is that we are not just surrendering our sovereignty: we are paying Mauritius billions of pounds for the privilege.

My central concern is the serious strategic challenge we face in respect of China. China has a population of 1.4 billion people and by 2030 its GDP is projected to be $26 trillion, second only to the US, and there are projections that it will potentially outstrip the US by 2050. China’s increase in military spending this year alone is expected to be 7.2%, which is the third consecutive year in which its increase in military spending has been over 7%. China has become the world’s largest shipbuilding nation, and its navy is expected to comprise 430 military grade ships by 2030, compared with the US navy’s estimated decline to 294 ships. China is a growing military power and there are no indications that it is anywhere near a supposed peak.

Domestically and internationally, China conducts itself as an autocratic state. It has the most sophisticated domestic surveillance system in the world, Skynet, which as of 2023 has 700 million cameras—that is one lens for every two Chinese citizens. We must not be so naive as to assume that if we end up in even greater strategic competition with China it will care at all about what agreement we have reached with Mauritius. We saw with Hong Kong how easily agreements made with third countries can be ignored, as China did there.

If Mauritius seeks to align itself strategically with China, do we think China will hesitate and ask it not to break the treaty because of international law? China will not respect any Bill or pay any attention to diplomatic consequences for Mauritius if it thinks it is in its interest to get Mauritius to break that agreement. That is the difference between any form of agreement and sovereignty, because once sovereignty has been given away, it can never be bought back.

This is why some people are concerned that if Mauritius allowed the Americans to have nuclear weapons on the base, although I do not think it would allow that, that would give China an excuse to break the same treaty to which Mauritius is already committed about a non-nuclear Africa, and China would not even get the odium that it otherwise would receive if it started deploying nuclear weapons all over the African continent.

My right hon. Friend is absolutely right. It is extraordinary that Labour Members are prepared to defend the deal, while admitting that they do not even know if our accusations are correct. They could say that they do not agree with what we are proposing, but to admit that they do not know whether nuclear weapons will be allowed on the island and that they are happy to support the deal anyway is disgraceful.

We must address the wider consequences of this decision. If Labour is willing to abandon the Chagos islands so easily, what message does that send to our other overseas territories? The International Court of Justice may have issued an advisory opinion in 2019—[Interruption.] What I say is true; the world is watching. We have had pressure put on us in relation to a sovereign territory and we have collapsed, but Labour Members want us to think that the rest of the world will not interpret our standing from that.

Ministers keep saying “How dare you compare this with the Falkland Islands?”, but Labour’s manifesto at the last election gave a commitment to defend the sovereignty of the British overseas territories—not some of them, all of them. If they cannot be trusted on this one, they cannot be trusted on any of them.

My right hon. Friend highlights the lessons that the rest of the world will be drawing from this decision.

A submissive approach to third party calls on these issues displays an incredible naiveté about the world we live in and the direction we are travelling. Our previous positive disposition towards the role that these institutions could play was in a different era, when we expected a converging uniformity of basic values and democracy. That convergence is not happening; instead, our enemies are using our desire to stick to it as a weakness to exploit. They do not even recognise basic legal norms and institutions in their own countries; their own citizens do not benefit from legal protections and rights, and they do not believe in the rule of law full stop.

Do the Government really think that our enemies will put international legal obligations ahead of pursuing their own strategic interests? Of course not, yet we are expected to undertake a strategic surrender in the name of the rule of law in a way that advantages them, and on what basis—that they might look at what we have done and change their ways in the future, as they failed to do in Hong Kong? That is incredible naiveté.
