Boris Johnson's time as Prime Minister hangs by a thread after a Tory MPs called for a confidence vote in his leadership.
His fate lies in the hands of more than 350 MPs who will get a say on if he fit to run the Conservative Party and be PM.
Johnson has faced criticism following the publication of the Sue Gray report into parties in Downing Street and Whitehall during the covid lockdown.
However, in the last 18 months Johnson has been heavily criticised on a number of occasions for his conduct in public and what he has said in private.
From his comments about coronavirus deaths to his handling of sleaze allegations it has been a year to forget for the PM who took over from Theresa May in 2019.
Here are the eight worst moments for Boris Johnson from the last 12 months:
'Let the bodies pile high'
In April last year it emerged that Boris Johnson said he would rather allow "bodies (to) pile high in their thousands" than impose another national lockdown across the UK.
It's believed he made the comments just after the announcement of a second lockdown at the end of October in 2020.
The reports were strongly denied by Downing Street saying it was "just another lie".
The comments caused outrage with many calling for him to apologise.
Not wearing face masks

Boris Johnson issued an apology in November when he was snapped not wearing a face mask while on a visit to a hospital in Hexham.
He told MPs: "There were barely 30 seconds when I wasn’t wearing a mask.
"I walked out of the room mistakenly not wearing it. I put it on as soon as I realised I had made the mistake. I apologise for that."
During the COP26 climate conference in Glasgow he was again pictured not wearing a mask while sat next to Sir David Attenborough.
According to the COP26 guidance attendees were told a mask must be on at all times except when eating, drinking, sitting in office/meeting spaces, conducting negotiations, giving speeches, or if medically exempt.
However it did say that "face coverings should be worn when sitting in theatre-style seating".
Euro 2020

The Prime Minister came under pressure in the lead up to and during Euro 2020 for failing to condemn fans who booed England players from taking the knee.
A number of Tory MPs and right-wing commentators were accused of stirring up more controversy which led Johnson to say the "whole country" needed to get behind the England team.
Johnson was also mocked for turning up to England's semi-final with Denmark wearing an England football top over his shirt and tie.
Matt Hancock
The former Health Secretary resigned the day after video footage emerged of him kissing an aide in his ministerial office in a breach of coronavirus restrictions.
Images and video showed Hancock in an embrace with aide Gina Coladangelo in May 2020, and Hancock was facing increasing pressure to quit over the breaking of social-distancing rules.
Boris Johnson was slammed by opposition and Tory MPs for not acting sooner to sack Hancock for breaching covid rules.
Dodging self-isolation
In July, Boris Johnson caved to public anger and agreed to self-isolate after having contact with health Secretary Sajid Javid who tested positive for covid.
He faced growing public fury after officials said Johnson and chancellor Rishi Sunak would avoid self-isolating like thousands of others because Downing Street took part in a pilot daily testing programme.
After widespread anger the Tory leader took just two hours and 42 minutes to perform a dramatic U-turn. He eventually did self-isolate.
Afghanistan

Boris Johnson's handling of the British evacuation from Afghanistan was slammed by opposition and Tory MPs as well as military veterans.
The Prime Minister was forced to admit his handling for the crisis would have been done better.
In an interview with broadcaster NBC, he said: "America has been there for 20 years and it’s a respectable argument to say that enough is enough. Look, I mean, could we have done it a bit differently? Maybe we could.”
Johnson was also criticised for allowing then foreign secretary Dominic Raab to remain on holiday while the Taliban rolled into the capital Kabul to take over the country.
Owen Paterson

In November, Johnson admitted it was a "total mistake" in trying to defend former North Shropshire MP Owen Paterson from punishment after he repeatedly broke lobbying rules.
In an evidence session he accepted that Paterson had done wrong.
It came after the PM attempted to rewrite the rules in order to get the former Environment Secretary off the hook. Johnson was slammed and performed yet another U-turn.
The scandal led to a by-election in December which the Lib Dems won. The swing of 34.2 per cent from Conservative to Lib Dem was the second largest since the war.
Lockdown fine

In April, Boris Johnson and his Chancellor Rishi Sunak were fined for attending the Prime Minister's birthday in Downing Street during the national lockdown.
Following the fine Johnson told the Commons: "I paid the fine immediately, and I offered the British people a full apology - and I take this opportunity on the first available sitting day to repeat my wholehearted apology to the House.
"As soon as I received the notice, I acknowledged the hurt and the anger - and I said that people had a right to expect better of their Prime Minister. And I repeat that, Mr Speaker, again in the House."
