Boris Johnson will try to shake off his Partygate hangover after Sue Gray's long-awaited report on lockdown boozing in Downing Street.
The top civil servant warned the Prime Minister must "bear responsibility" for the culture in No10 and Whitehall during the pandemic, with examples of vomiting, a fight, karaoke, wine spilled up walls, and security and cleaners with a lack of respect by staff.
Mr Johnson is trying to brazen it out by offering a half-hearted apology for getting fined for his surprise birthday bash and trying to shift blame onto his staff by claiming the extent of rule-breaking was "news to me".
The PM has repeatedly defied calls to quit and told a press conference: "I overwhelmingly feel it is my job to get on and deliver."
But Mr Johnson isn't safe yet.
Privileges Committee investigation
MPs on the powerful Privileges Committee are investigating whether he misled Parliament by repeatedly denying that Covid rules had been broken in Downing Street.
The committee has the power to demand photographs and documents - and to summon witnesses to give evidence.
Misleading Parliament is serious offence, and politicians who do so knowingly are expected to resign in line with the ministerial code.
This will be a tricky one for Boris Johnson as he repeatedly denied that parties had taken place or that rules had been broken.
The Met Police and now Sue Gray have now shown this is not the case.
Crunch by-elections
Mr Johnson must also fight two critical by-elections next month, prompted by resignations over Tory sleaze.
The Tories are facing a Red Wall battle against Labour in Wakefield, West Yorkshire, after MP Imran Ahmad Khan was jailed for sexually assaulting a teenage boy.
In the south, the Liberal Democrats are eying Tiverton and Honiton in a by-election triggered by the resignation of "porn Tory" Neil Parish, who admitted to watching X-rated material in the Commons.
The results will be crucial to proving to his party that he's still an electoral asset who can lead them into the next election.
Nervous Tories will be watching to see if he can hold onto gains made from Labour in 2019 in the North and the Midlands, while retaining seats in the Conservatives' southern heartlands.
Tory dissent
His major challenge is wooing back fed-up Tory MPs.
Months of Partygate headlines and rising cost of living pressures have left some feeling mutinous.
Conservative MPs are the ones who keep the PM in power - and the ones who can take that away.
It only takes 54 MPs to write no-confidence letters to 1922 Committee chairman Sir Graham Brady for a vote to be held.
