Prime Minister Rishi Sunak was fined for not wearing a seatbelt in a moving car while making a social media video.
Lancashire Police said it had made a conditional offer of a fixed penalty to a 42-year-old man from London.
No. 10 said Mr Sunak “fully accepts this was a mistake and has apologised,” adding that he would pay the fine.
A £100 fine can be imposed on passengers who are found to not be using a seat belt when one is available.
If the case gets to court, the fine might be increased to £500.
The deputy prime minister described Mr. Sunak as “someone with the highest standards of integrity” who “made a mistake on the seatbelt issue” in a BBC Breakfast interview.
Dominic Raab said the PM was “a human being doing a demanding job” and had “put his hands straight up” and apologised.
The video was shot in Lancashire as the prime minister was on a journey across the north of England.
The video was uploaded to Mr. Sunak’s Instagram account to promote the government’s most recent round of “levelling up” spending.
This is Mr Sunak’s second fixed penalty notice while in government.
He was fined last April along with Boris Johnson and his wife Carrie for violating the Covid lockdown regulations by going to the then-prime minister’s birthday party in Downing Street in June 2020.
