UK Prime Minister Boris Johnson is fighting to shore up his premiership as he faces the publication this week of an investigation into boozy parties at the heart of the British state during COVID-19 lockdowns.
Johnson, who in 2019 won the biggest Conservative majority in more than 30 years, is now assailed by scandal, facing claims he and his staff partied during the worst pandemic for a century and a new accusation of racism in his party.
The results of an official investigation by Cabinet Office official Sue Gray into the lockdown parties is due to be published later this week.
Johnson has given a variety of explanations about the parties: first he said no rules had been broken but then he apologised to the British people for the apparent hypocrisy of such gatherings.
Police officers who guard Downing Street have been interviewed by Gray and have given "extremely damning" evidence, The Telegraph newspaper reports, citing an unidentified source.
Johnson has denied a claim he was told a "bring your own booze" lockdown gathering on May 20, 2020, which he says he thought was a work event, was inappropriate.
His former senior adviser Dominic Cummings - now a harsh critic - is due to be interviewed on Monday.
Toppling Johnson would leave Britain in limbo for months just as the West deals with the Ukraine crisis and the world's fifth largest economy grapples with a once-in-a-generation inflationary wave triggered by the pandemic.
To trigger a leadership challenge, 54 of the 359 Conservative MPs in parliament must write letters of no confidence to the chairman of the party's 1922 Committee.
Leading rivals within the Conservative Party include Chancellor of the Exchequer Rishi Sunak, 41, and Foreign Secretary Liz Truss, 46.
Johnson on Monday ordered an inquiry into claims by an MP who said she was fired from a ministerial job in the government partly because her Muslim faith was making colleagues uncomfortable.
Nusrat Ghani, 49, who lost her job as a junior transport minister in February 2020, told the Sunday Times that she had been told by a "whip" - an enforcer of parliamentary discipline - that her "Muslimness" had been raised as an issue in her sacking.
"The prime minister has asked the Cabinet Office to conduct an inquiry into the allegations made by Nusrat Ghani MP," Downing Street said.
"As he said at the time, the prime minister takes these claims very seriously."
The government's chief whip, Mark Spencer, said he was the person at the centre of Ghani's allegations. He said they were completely false and defamatory.
Ghani's allegation came after one of her Conservative colleagues said he would meet police to discuss accusations that government whips had attempted to "blackmail" MPs suspected of trying to force Johnson from office.
