BORIS Johnson and Rishi Sunak will both be fined over parties held on Downing Street while the rest of the UK was in lockdown.

A No 10 spokesperson said: “The Prime Minister and Chancellor of the Exchequer have today received notification that the Metropolitan police intend to issue them with fixed penalty notices.

"We have no further details, but we will update you again when we do.”

The spokesperson said they had not been notified of which lockdown-breaking event the fixed penalty notices were being issued for.

The news has been rapidly followed by calls for Johnson to step down.

Scotland's Constitution Secretary Angus Robertson wrote: "The Prime Minister has broken the law. 

"He must now resign."

Ian Blackford, the SNP's Westminster leader, called on Sunak to follow Johnson out, saying the two had "lost the trust and moral authority to lead".

The MP said Johnson had "misled parliament, lied to the public, and broken the law".

Keir Starmer, Labour's leader, also called for the pair to resign. He wrote: "Boris Johnson and Rishi Sunak have broken the law and repeatedly lied to the British public. 

"They must both resign.

"The Conservatives are totally unfit to govern. Britain deserves better."

The news comes after the Met Police confirmed that more than 50 fines were to be handed out for breaches of the regulations.

At least 30 more fixed penalty notices will be issued by the ACRO Criminal Records Office, the Metropolitan Police said in its latest update on Operation Hillman, which is looking into breaches of Covid-19 regulations.

This is up from the 20 referrals for fixed-penalty notices (FPN) the force said had been made at the end of March.

Johnson is understood to have been present at six of the at least 12 events being investigated.

Westminster is currently in recess, with MPs due to return to the House of Commons on April 19.
