Boris Johnson will face a vote of confidence later in the day.
To get a vote of confidence, 15% of Conservative lawmakers have to write a letter to Graham Brady, chairman of the 1922 Committee which oversees the party's leadership challenges.
Brady said that the threshold had been reached.
Between 6 p.m. and 8 p.m., the vote will be held. There are times in London when it is 1 p.m. and 3 a.m. There is an event taking place.
The release of a report into several high-profile Covid-19 parties at Johnson's office and residence sparked calls for a confidence vote.
The vote tonight is a chance to end months of speculation and allow the government to draw a line and move on, according to a statement released by a spokesman for the prime minister.
The statement said that the prime minister would remind lawmakers that there is no more formidable political force if they focus on the issues that matter to voters.
The prime minister has the support of some Conservatives. The foreign secretary said that Johnson had her full support.
He has supported Ukrainians in the face of Russian aggression. He has apologized for his actions. She said we need to focus on economic growth.
Johnson will be protected from a second vote of confidence for another year if he wins the vote.
Johnson will have to step down if he loses the vote. Johnson won't be allowed to stand in that situation.
Despite murmurs of discontent within the Conservative Party over Johnson's leadership, he has shown no inclination to step down.
There is a breaking news story that will be updated soon.
