Sir Julian Lewis: Given the Prime Minister’s unequivocal backing of Ukraine, and his admirable assertions that Putin must be seen to fail, will he rule out replacing, if she has to be replaced, our professional diplomatic ambassador in Washington with a party politician who has stated that Ukraine must lose the occupied territory to Russia, give up on becoming a member of NATO, and rely instead on security guarantees from European states?

[The Prime Minister: I thank the right hon. Gentleman for the joint position in relation to the importance of Ukraine. I will resist the temptation that he offers for me to start discussing the position that he referenced.]
