Contribution

Just to make a small comment on the previous speech, I have been here a little while, and I have never once stopped regretting taking a Government handout to speak in support of the Government, because more often than not, it rebounded on me. As my right hon. and learned Friend the Member for Kenilworth and Southam (Sir Jeremy Wright) and many others have made clear, there are two elements to this issue. Before I start on that, I want to say something about the Chagossians. They are the last people to have been seriously consulted about any of this. The way that we behaved to them back in the 1960s was appalling. It should never have happened, and there was no need for it to have happened. They should have been able to stay on the archipelago, and we should have supported them in that. They must be a part of this. I know that they are very fearful of this deal as it stands. My other point is that this arrangement is vague about what happens after 99 years. We are supposed to guess, or believe that we can trust Governments to make the right decisions. The statement on the rights of the Chagossians is completely missing a sense of where they will be, what they want and how we will bring that about. I pay tribute to the Member who made a good intervention on that point. Let me quickly deal with the legal case, and then I will discuss the cost, and China and Russia. The Government have been peppered with requests non-stop since this process began to explain the legal threat that meant that we would be in real trouble if we did not seal a deal—any deal. Right the way along, they would not exactly explain. There were little suggestions here and there that a judgment would lead to certain things. My right hon. and learned Friend the Member for Kenilworth and Southam has been absolutely right on that. Today, I thought that the door slightly opened. I have known the Minister of State, Foreign, Commonwealth and Development Office, the hon. Member for Cardiff South and Penarth (Stephen Doughty), for a long time, and his name is a good description of his solidity and purposefulness. The Minister who opened the debate, the hon. Member for Plymouth Sutton and Devonport (Luke Pollard), made the point that the legal threat was to do with UNCLOS. I was intrigued by that, because, as I just said to my right hon. and learned Friend the Member for Kenilworth and Southam, within UNCLOS, clear for all to see, is a complete let-out for the UK Government when it comes to the case that they suggest would be brought against them under UNCLOS. The threat simply does not exist. I repeat that there are two exemptions, under article 298(1)(b) and 298(1)(c). The first has the UK opted out of “disputes concerning military activities…by government vessels and aircraft engaged in non-commercial service, and disputes concerning law enforcement activities”. The same applies under 298(1)(c) in relation to matters taken up by the UN Security Council. The important point is that the threat does not need to be recognised, because ultimately this comes back to the original International Court of Justice ruling. That was an advisory judgment, because the Court cannot make an absolute judgment on anything to do with our relationships with the Commonwealth, either existing or previous; that is an important point. We keep coming back to this check on what would happen. The idea that everybody will dispute with us on that is simply nonsense. From a legal perspective, I think the Government have come unstuck in this debate. I have sat through many debates in this House, and it is rare that a Government completely come unstuck on a case of legalities. The second bit that the Government have come unstuck on is the money. On the legal side, they will not tell us exactly what the situation is. There have been hints, proposals and suggestions that somehow we were in a desperate situation. On the money, I have never seen a Government as unable or unwilling to tell us exactly how much things cost or are worth. They are normally quick to do so, and to blame the other side, or whatever—it does not really matter. Everybody has been chasing the Government for that information, and now we discover that they have gerrymandered the figures for the overall statement. The total cost is nearly £35 billion, and we need to deal with total cost. Let me remind the Government of the problem with what they call the GDP deflator and the so-called social time discounting method. The Government Actuary’s Department has dismissed that as a real way of calculating cost for this kind of issue, and it has re-emphasised the fact that understanding the total cost is the only way to look at a long-term treaty. The Government is relying on the cost-benefit analysis used for social projects. There is particular concern about long-term projects, and a real dispute about whether such a method can predict precisely, or even reasonably well, the overall cost in the long term. There is a lot of concern about whether that is the right way to go. Add to that the fact that the Government are trying to predict what will happen in Mauritius, under the Mauritian Government, over the next many years. This is a 99-year deal, and there is no way on earth that we have any control.
