Dr Julian Lewis: Although Mr Farage has ruled himself out, the question still arises of what the effect would be if Sir Kim [Darroch] felt that his position had become untenable and, instead of retiring in a few months’ time as planned, he had to go earlier. One effect would surely be that an outgoing Prime Minister had a say in the replacement, rather than the new Prime Minister. Would it not be sensible for Sir Kim to be encouraged to stay in post, so that there is no temptation for an outgoing Prime Minister to appoint to a plum job one of her inner circle?

[The Minister for Europe and the Americas (Sir Alan Duncan): I have no wish whatsoever to comment on the process by which any future ambassador to Washington will be chosen. All I will say is what I said earlier: we have full confidence in Sir Kim Darroch, and he retains the entire confidence of the Government and all of us who serve as Ministers in the Foreign Office.]
