Sir Julian Lewis: I have a lot of respect for the hon. Lady, and that is why I will have one more go at this: is there any court, other than the ICJ, that could come to a judgment against Britain over the sovereignty of the islands?

[The Parliamentary Under-Secretary of State for Foreign, Commonwealth and Development Affairs (Catherine West): As the right hon. Member is aware, given his long background in intelligence, the lack of legal certainty is why we have acted. The base cannot operate in practical terms as it should. It is bad for our national security, and a gift to our adversaries, if we fail to secure legal certainty for the base.]
