Boris Johnson has been told he will not receive any more Partygate fines from the Metropolitan Police.
Downing Street said the force had confirmed that they would not be issuing any further fixed penalty notices to the Prime Minister after they wrapped up their probe.
Mr Johnson has already received a fine over his surprise lockdown birthday do in June 2020, along with his wife Carrie and Chancellor Rishi Sunak.
Scotland Yard confirmed it had issued 126 fines to 53 men and 73 women - with some people getting more than one - over law-breaking parties in Downing Street and Whitehall on eight separate dates during the pandemic.
Police were looking at 12 parties on these eight dates, but they have not confirmed which gatherings have resulted in fines.
The PM's official spokesman said: "The Met has confirmed they are taking no further action with regards to the Prime Minister."
Asked if he had only received one fine, the spokesman said: "That’s correct."
His wife Carrie has also been informed she won't get further fines.
The Met spent £460,000 on it's Operation Hillman probe into Partygate, where officers investigated events on eight dates spanning 11 months.
It hasn't specified which gatherings have resulted in fines, as we know there was more than one party on two of the dates.
Six of the 12 events, the ones marked with an asterisk (*), were said to have been attended by Boris Johnson.

Top civil servant Sue Gray is expected to publish her report into the Partygate scandal next week.
A source close to the investigation told the Mirror: "It won't be this week. We've always said that we would publish as soon as the Met investigation concludes.
"We've also said before that we would want to do it when the House is sitting. So realistically it would be next week."
Downing Street said the Prime Minister will update Parliament when the Sue Gray report is published.
The PM's official spokesman said: "I would say the Prime Minister is pleased the investigation has concluded and we'd like to thank the Met Police for their work in bringing this investigation to completion.
"Beyond that ... I think the Prime Minister will update Parliament in the first instance on the publication, once Sue Gray's report is published, and that's when he will talk in more detail."
