BORIS Johnson could face another no confidence vote within days if the Tory party goes ahead with a change of rules.

The Prime Minister is immune from a leadership challenge for a year under current party rules after winning the support of enough MPs a month ago.

The 1922 Committee of Tory backbenchers is expected to move to allow another confidence vote, with reports there are enough letters already in from Tory MPs to trigger a fresh ballot.

The election of new 18-member executive to the committee is anticipated to take place on Monday, according to Tory MP Alec Shelbrooke.

Voting will take place on Monday afternoon and the result announced in the evening.

Any rule changes would be discussed by the new executive.

Johnson narrowly survived a vote of confidence last month with 211 MPs voting for him, compared to 148 against.

He needed a majority of 180 votes or more to continue in office.

Speaking after attending the 1922 Committee meeting, Tory MP Sir Roger Gale told Sky News he believed party backbenchers would have to act to remove the Prime Minister as he was unlikely to resign.

“I fear that given the nature of the man, the 1922 committee will have to change the rules and we will have to have a vote of no confidence,” he said.

“It would be much more dignified for the Prime Minister…if he were to simply understand the situation and leave with dignity and quietly.”

Asked if he believed that Johnson would stay even if Cabinet ministers suggested to he should leave office, Gale said: “I fear it is the nature of the man we are dealing with.

“He seems determined to cling on for as long as he possibly can – I don’t think that’s dignified, I don’t think it is a sensible way forward.

“He needs to consider first the country, second his party and third those close to him. If he does all of that then sensibly he would resign and clear the pathway for someone else to be elected and take over the government and take us forward.”

He added: “Let us hope that common sense will prevail. But if it doesn’t, we are going to have to take the hard road forward.”

On the issue of whether there were enough MPs who would vote to change the rules in the 1922 committee, Gale said he believed there was an “overwhelming majority” of members of the parliamentary party who believe “this is the endgame”.

But he added: “It would be quite wrong of me to suggest that there aren’t also people even now who feel Mr Johnson should remain in office.

"That is where the division lies.”
