The Tory MPs known to have sent a letter of no confidence in May

This is a list of Conservative MPs who have publicly said they had sent in letters demanding a vote of no confidence in Theresa May’s leadership. Those named have released their letters on social media, or told the media they have sent in a letter.

A total of 48 MPs need to have written in for a vote to be triggered. The vote would be held a couple of working days after the threshold had been reached. May would then need to win the backing of half or more of her MPs – 158 – to ensure that she kept her job as party leader, and hence prime minister.

The true number of letters that have been sent in is almost certainly higher. There is no obligation for MPs to disclose whether they have sent in letters to the chairman of the party’s backbench 1922 Committee, Sir Graham Brady.

But Brady has no obligation to disclose how many letters have been sent to his office until the magic number of 48 is reached, whereupon he would tell May and publicly announce that a ballot would be held.
