LONDON (Reuters) - Alistair Burt, a junior minister in Britain’s Foreign Office, urged his Conservative colleagues on Thursday not to submit letters of no confidence in Prime Minister Theresa May.

Burt was speaking outside a meeting of influential eurosceptic Conservative lawmakers, including Jacob Rees-Mogg who plans to put in a letter of no confidence later on Thursday.

Asked what he would say to those considering putting letters in, Burt said: “Please don’t. We have a leader, she’s worked incredibly hard on the most difficult deal.”
