ENOUGH Tory MPs have requested a vote of confidence in Theresa May to trigger a contest amid the ongoing Brexit chaos.

Chairman of the backbench 1922 Committee, Sir Graham Brady said a ballot would be held between 6pm and 8pm on Wednesday in the Commons.

He added in a statement: "The votes will be counted immediately afterwards and the result will be announced as soon as possible in the evening."

Moments after news of the vote was announced, Foreign Secretary Jeremy Hunt tweeted: "I am backing @theresa_may tonight. Being PM most difficult job imaginable right now and the last thing the country needs is a damaging and long leadership contest.

In a joint statement the chairman of the European Research Group Jacob Rees-Mogg and his deputy Steve Baker said: "Theresa May's plan would bring down the Government if carried forward. But our party will rightly not tolerate it.

"Conservatives must now answer whether they wish to draw ever closer to an election under Mrs May's leadership. In the national interest, she must go."

Home Secretary Sajid Javid said: "The last thing our country needs right now is a Conservative Party leadership election. Will be seen as self-indulgent and wrong. PM has my full support and is best person to ensure we leave EU on 29 March."

Sir Graham Brady 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."
