Sir Julian Lewis: I am a great admirer of the hon. Gentleman [Tim Roca]; he is courteous and thoughtful, and I always listen to what he says with great focus and attention. He is criticising the dangers of ambiguity, and I agree with that point. Does he accept, however, that we have not cleared up the ambiguity about whether nuclear weapons could ever be on Diego Garcia if the Americans and the British wanted them to be? It is no good saying, as the Minister did, “We never talk about deployments of nuclear weapons.” We are not asking about deployments of nuclear weapons. We are asking about the legal position if the case was that the Americans or the British wanted to have nuclear weapons, temporarily or permanently, on Diego Garcia. If we transfer sovereignty to a country that is signed up to be part of a nuclear-free zone, that is bound to call into doubt the ability to have nuclear weapons there in the future. Can he clear up that point?

[Tim Roca: I cannot clear up that point for the right hon. Member, but I have great confidence that ministerial colleagues would be able to. We have been told at all points that this treaty would ensure the continued effectiveness of the base in the way that it is run now. There was an Ohio class submarine there in 2022, and I hope those arrangements continue under this treaty. From what I have heard from Ministers, there is no reason that they would not. …]
