Police have told British Prime Minister Boris Johnson he faces no further action over lockdown breaches, Downing Street said, after the Metropolitan Police concluded its partygate investigation with a total of 126 fixed-penalty notices.

The Metropolitan Police said earlier it had issued fixed-penalty notices (FPNs) for events in Downing Street and across Whitehall spanning eight separate days, with 28 people receiving between two and five fines.

No 10 said the Prime Minister was "pleased" the investigation had concluded and that officers had told Mr Johnson he would not receive a second fine, having received one for the event on his 56th birthday.

The conclusion of Operation Hillman into partygate breaches spanning 11 months paves the way for the publication of senior civil servant Sue Gray's inquiry.

It was understood Chancellor Rishi Sunak was also yet to receive another fine, after receiving one for attending the Prime Minister's gathering in June 2020.

The Prime Minister's wife Carrie Johnson has also received confirmation she faces no further action.

The Prime Minister's official spokesman said: "The Met has confirmed that they are taking no further action with regards to the Prime Minister."

Scotland Yard said in a statement that of the fines issued for breaching Covid restrictions, 73 were to women and 53 to men.

Police were called in to investigate gatherings at Downing Street and across government departments on eight dates between May 2020 and April 2021.

Last week, the force said it had issued more than 100 fines.

The exact amount of the penalties has not been confirmed, but the fines can range from £30 to £10,000 (€35-€11,800) for the most serious breaches.

Those fined so far include Mr Johnson, his wife Carrie and finance minister Rishi Sunak.

The government said they were fined for a gathering in Downing Street marking the prime minister's birthday in June 2020.

The probe was launched on 25 January and saw 12 detectives sift through 345 documents, including emails, door logs, diary entries and witness statements, 510 photographs and security camera footage and 204 questionnaires, the Met said.

"When Covid regulations were introduced, the Met was clear that whilst we would not routinely investigate breaches of regulations retrospectively, there may be occasions when it would be appropriate to do so," said the Met's Acting Deputy Commissioner Helen Ball.

"The information that we received with regard to the alleged breaches in Downing Street and Whitehall was sufficient to reach our criteria to begin such an investigation.

"Our investigation was thorough and impartial and was completed as quickly as we could, given the amount of information that needed to be reviewed," she said.

"This investigation is now complete."

Mr Johnson has apologised for the breach of Covid regulations, but refused demands to resign after becoming the first UK leader to be found to have broken the law while in office.

Mr Johnson also faces an investigation by a parliamentary committee into his past denials to the House of Commons of lockdown lawbreaking.

The parties have fuelled widespread public anger against the ruling Conservatives, who suffered a drubbing in recent local elections.

The main opposition Labour party's leader, Keir Starmer, has promised to step down if police in northeast England fine him for his own alleged breach of coronavirus laws during a campaign meeting.

The gathering took place in Durham in April last year, with a video later emerging of Mr Starmer drinking beer and eating a takeaway meal inside an office with party colleagues.

Labour has called for the full publication of the Sue Gray inquiry into partygate after Scotland Yard finished its investigation.

Deputy leader Angela Rayner said: "Industrial scale rule breaking has taken place at the heart of Boris Johnson's Downing Street.

"We must now urgently see the Sue Gray report published in full. It's time for the Prime Minister to stop hiding.

"While the British people sacrificed so much, Boris Johnson's Downing Street broke the rules at record-breaking scale. Britain deserves better."
