My right hon. Friend is right. From memory, I think he is referring to article 3 of the 1996 treaty, which explicitly talks about researching and so on. The Government need to set out the implications and how that treaty interacts with this treaty that they are signing or want us to ratify. Let us step back a bit further. We are in this position, the Government argue, because of a non-binding ICJ judgment. I will ask the Minister again: with which court does he believe there would be a problem? The Government have said time and again that we could be brought into conflict with several courts. The Defence Secretary was worried about the United Nations convention on the law of the sea and the International Tribunal for the Law of the Sea, but we already know from a 2015 ruling against the UK over Mauritius that they cannot judge sovereignty, so that one is out the window. Earlier, I asked the Minister, the hon. Member for Feltham and Heston (Seema Malhotra) about this issue, and she mentioned the 2021 special chamber of the International Tribunal for the Law of the Sea. As she will know, the UK was not party to give information to that, and it rested on the non-binding judgment of the ICJ, which is already contested. There is an opt-out, because it is a Commonwealth interaction. Months on, the Government still cannot answer these simple questions. Another body that is often referred to—we will go over this again—is the International Telecommunication Union. We know from the Government’s own written answers that article 48 of the ITU constitution states that it cannot judge sovereignty. The Government know that, and I do not understand why they will not just stand here and say that. On finances, the figures and what they are made up of is contested. The Government are right on their figure, and the Opposition are right on our figure, but how can that be? It is because of the mechanism being used to judge that value. The Opposition contest that the best way to work out the figure is the nominal value used by the Government actuaries. The deal is over 100 years, and we have to take into account what things will look like and other factors. The Government actuaries say that the cost is £34 billion, yet the Government are using net present value, which gives us £3.4 billion. I am glad that the Minister for Defence Readiness and Industry is here, because I posed this question to him in the last debate, and his answer was that the figure is in the Green Book. I retorted: “Can the Minister point to any other country in the world that has used NPV to give away sovereignty?”—[Official Report, 9 September 2025; Vol. 772, c. 748.]
