Boris Johnson has received a questionnaire from police investigating allegations of lockdown-breaching parties in Downing Street.
No 10 confirmed on Friday evening that the Prime Minister had received the legal form from Metropolitan Police officers, and said he will “respond as required”.
The move means Mr Johnson will have to provide a credible reason as to why he was at events held during coronavirus restrictions or face a fine.
A No 10 spokeswoman said: “We can confirm the Prime Minister has received a questionnaire from the Metropolitan Police.
“He will respond as required.”
It comes after the Chancellor appeared to suggest that he does not expect to be asked to fill out a police questionnaire about his involvement in an event that possibly broke coronavirus lockdown rules.
Rishi Sunak has confirmed he was at the surprise birthday celebration for the Prime Minister on June 19 2020 in the Cabinet room in No 10, but has said he was only there for a scheduled Government meeting.
Mr Sunak, asked by Sky News whether he had received a questionnaire from the Metropolitan Police, said: “No.”
Asked whether he expected to receive a form to complete, he replied: “No… well, I don’t know.”
He also said he did not think he had broken Covid rules.
Pressed on whether he has confidence in Boris Johnson still, Mr Sunak added: “The Prime Minister has my total support.”
