Sir Julian Lewis: My hon. Friend is making an excellent speech, but I think he knows the answers to those simple questions. The answer to the question whether Mauritius could stop us having nuclear weapons stored on Diego Garcia is clearly that it would be able to do so. It is clear that the answer to what happens if the Americans say no to changing the 1966 agreement is that this deal to get rid of our sovereignty over the Chagos islands would be dead in the water. The reason that Ministers will not say those things, even though they know them to be true, is that they are afraid of a headline saying, “Minister admits that Chagos surrender can’t go ahead without American agreement”.

[Dr Luke Evans: My right hon. Friend is entirely right in pinpointing some of the issues, and I will reverse my speech and deal with some of those first. …]
