Boris Johnson faces more questions about No 10 parties from MPs later, as the results of an internal inquiry into possible lockdown breaches are due.
It is understood the highly-anticipated report, by senior official Sue Gray, is largely complete and could be published as early as Wednesday.
But it is not expected to be revealed ahead of Prime Minister’s Questions at noon.
It comes after the Met Police announced its own investigation on Tuesday.
Commissioner Cressida Dick said the force was looking into potential breaches of Covid laws at a number of events in government buildings since 2020.
The police probe heaps further pressure on the PM, after weeks of headlines about gatherings in Downing Street when laws preventing social mixing were in place.
The PM has apologised for attending a “bring your own booze” event on 20 May 2020, during the first lockdown, saying he thought it was a “work event”.
Fresh allegations of a birthday party being held for the prime minister in June 2020 have also come to light.
