Boris Johnson facing leadership crisis after at least 54 of his own MPs submit letters of no confidence

• UK Prime Minister Boris Johnson is due to face a leadership vote Monday evening.
• At least 15% of Conservative members of Parliament submitted secret letters of no confidence.

Boris Johnson is in the midst of a leadership crisis, with the prime minister facing a vote of no confidence on Monday evening.

Graham Brady, the senior Conservative backbencher overseeing the process, confirmed that he had received enough letters of no confidence to trigger a vote in Johnson's leadership.

"The threshold of 15% of the parliamentary party seeking a vote of confidence in the leader of the Conservative Party has been exceeded," Brady said in a statement.

At least 54 Conservative members of Parliament were required to submit letters to meet that 15% threshold. Sources told Insider they believed more than 60 had done so, although Brady declined to comment.

Brady said the vote would take place between 6 p.m. and 8 p.m. on Monday.

Downing Street was bullish in response to the vote, describing it as an opportunity to "draw a line and move on."

A spokesperson said Johnson would remind MPs that "there is no more formidable political force" in British politics.

Speaking to journalists immediately after publishing his statement, Brady said the vote would take place in the House of Commons and the results would be announced "shortly thereafter."

"I notified the prime minister yesterday that threshold had been reached and we agreed a timetable," he said.

"He shared my view, which is also in line with the rules that we have in place, that the vote should happen as soon as reasonably could have taken place."

Brady said some of his Tory colleagues had "asked specifically it should not be until after the jubilee celebrations" — appearing to confirm what sources had told Insider last week.

The announcement came after another senior MP published a letter of no confidence Monday morning.

Jesse Norman, a former Treasury minister, went public with an excoriating letter criticizing Johnson for several facets of his leadership and recent policies.

It included "ugly" plans to send asylum seekers to Rwanda, as well as the so-called Partygate scandal in which Johnson and those around broke rules to hold parties in the UK's coronavirus lockdowns.
