British Prime Minister Boris Johnson has received a legal questionnaire from police investigating claims of lockdown-breaking parties in his Downing Street office, his spokesman said Friday.

“We can confirm the prime minister has received a questionnaire from the Metropolitan Police. He will respond as required,” his spokesman said in a statement.

The “partygate” scandal has placed Johnson in political jeopardy with several MPs from his Conservative party publicly calling for his resignation, although he denies any wrongdoing.

Police confirmed on Wednesday that they would be sending “formal questionnaires to more than 50 people” by the end of the week to ask about their activities on the dates of at least 12 gatherings in Downing Street over 2020 and 2021.

The document “has formal legal status and must be answered truthfully” within seven days, the police noted.

Johnson faces a fine unless he can give credible reasons as to why he was at events held during coronavirus restrictions.

British ex-premier John Major on Thursday accused Prime Minister Boris Johnson of breaking Covid laws and fostering public “contempt” for politics.

Major is the second of Johnson’s Conservative predecessors in the post to criticise him over the revelations.

Last week, Theresa May told parliament a civil servant’s report into the events showed that Downing Street “was not observing the regulations they had imposed on members of the public”.

She asked Johnson to clarify whether he “had not read the rules or didn’t understand what they meant… or they didn’t think the rules applied to Number 10”.

Johnson has already apologised in parliament for a series of gatherings identified in an official inquiry led by senior civil servant Sue Gray, but vowed to fight on in office.

Gray’s report led to a clear out of the prime minister’s top team.

“I’m sorry for the things that we simply didn’t get right, and also sorry for the way this matter has been handled,” Johnson told parliament.

“I get it, and I will fix it,” he said.

“Yes, we can be trusted to deliver,” Johnson added, stressing his post-Brexit agenda and action against Russia over its threats to Ukraine.

“I am going to get on with the job.”

Gray admitted her 12-page report was limited in scope after London’s Metropolitan police force launched its own investigation into 12 parties held in Downing Street over the past two years.

While Johnson said all sides should await the Met’s own findings, opposition Labour leader Keir Starmer said the police involvement was “a mark of shame”.

“He is a man without shame,” Starmer said, urging Johnson’s Conservative cabinet allies to depose him instead of “supporting further misconduct, cover-up and deceit”.
