United Kingdom Prime Minister Boris Johnson will face a vote of confidence.
Conservative Party MP Sir Graham Brady, chair of the 1992 committee, said on Monday the ballot will be held between 6pm - 8pm on Monday (local time).
"The threshold of 15 percent of the parliamentary party seeking a vote of confidence in the leader of the Conservative Party has been exceeded."
The BBC reports Brady notified Johnson on Sunday (local time) but wouldn't go into the detail of his reaction.
Brady told media outside the House of Parliament that Tory MPs "asked specifically that it should not be until the end of the Jubilee celebrations," the BBC reports.
The vote of confidence in Johnson is due to take place later on Monday and will provide a chance to end months of speculation about his leadership, a spokesperson for Johnson said.
"Tonight is a chance to end months of speculation and allow the government to draw a line and move on," the spokesperson said in a statement.
"The PM welcomes the opportunity to make his case to MPs (members of parliament) and will remind them that when they're united and focused on the issues that matter to voters there is no more formidable political force."
British foreign minister Liz Truss said she was backing Prime Minister Boris Johnson in the confidence vote.
"The Prime Minister has my 100 percent backing in today's vote and I strongly encourage colleagues to support him," Truss said on Twitter.
"He has delivered on COVID recovery and supporting Ukraine in the face of Russian aggression. He has apologised for mistakes made. We must now focus on economic growth."
Truss has been considered as a potential successor to Johnson.
The BBC reflected on the last time the Tories held a confidence vote. This was in December 2018 when the then Prime Minister Theresa May came under growing criticism on her delivery of Brexit.
Fifteen percent of her MPs declared their no confidence in her leadership, so a vote was called, the BBC said.
May won the vote, with 63 percent of MPs supporting her.
By May 2019, she was unable to deliver Brexit and announced her resignation as Tory leader the following month.
Johnson has been the leader since July 2019.
