48 letters needed to trigger a vote of no confidence against Theresa May has officially been reached.

Theresa May will face a vote of no confidence this evening in the House of Commons.

If she loses the vote she will face a leadership election, most likely against Brexiteer Boris Johnson.

The ballot will be held from 6pm to 8pm this evening.

The chairman of the backbench 1922 committee of Conservative MPs said: “The threshold of 15% of the parliamentary party seeking a vote of confidence in the leader of the Conservative Party has been exceeded.

“In accordance with the rules, a ballot will be held between 1800 and 2000 on Wednesday 12th December in committee room 14 of the House of Commons.

“The votes will be counted immediately afterwards and an announcement will be made as soon as possible in the evening.

“Arrangements for the announcement will be released later today.

“I will be available to answer questions about this process on Abingdon Green from 0800 hrs.”

Political Correspondent for Sky News, Tom Rayner yesterday claimed that an MP told him that 4 or 5 letters of no confidence were submitted in the past 24 hours.

He said: “Tory MP who has already submitted a no-confidence letter tells me he thinks “4 or 5” additional letters have been sent to Sir Graham Brady in last 24 hours. BUT plenty of caution in westminster too – one critic of PM not thought to have submitted a letter yet was v doubtful”.

Beth Rigby yesterday predicted the no confidence vote, tweeting: “Confidence vote watch. I know it’s a dangerous game to play and Sir Graham is keeper of the list. But my ERG sources pretty confident now that 48 trigger been breached. Of course Sir Graham won’t announce while PM out of country – and we’ve been here before. But mood hardening”
