Conservatives who have sent a letter of no confidence and those who have publicly urged the PM to stand down

Boris Johnson was warned he would face a string of no-confidence letters after the Sue Gray report into Partygate concluded. In order for a vote of no confidence to be triggered, the chair of the 1922 Committee, Graham Brady, must receive letters from at least 54 Conservative MPs - 15% of the parliamentary party.

Here is the full list of Tory MPs who have urged the prime minister to stand down, though some say they have not written letters to Brady. Several other critical MPs say they will not reveal whether they have sent a letter - so the true number is likely to be higher.
