The BBC has canceled a prime-time interview with Boris Johnson after presenter Laura Kuenssberg accidentally sent the former prime minister her briefing notes.

Kuenssberg said she sent Johnson the notes “in a message for my team.” The BBC’s former political editor said it was “embarrassing and disappointing” and added the error meant it was “not right to continue with the interview”.

It was due to air on BBC One at 7.30pm on Thursday and was thought to be Johnson’s first major interview since leaving office. He was expected to speak about Brexit, his government’s handling of the Covid pandemic and the Partygate scandal.

Other broadcasters and podcasters have offered to do the interview in Kuenssberg’s place, while the BBC has been asked to use another journalist. Among the volunteers who conducted the interview

Sunder Katwala, director of the think tank British Future, also called on the BBC to find a replacement to conduct the interview. “Shouldn’t the BBC just get someone else to do the interview on Friday or next week?” he said on X.

Johnson, who was prime minister from 2019 to 2022, will publish his memoirs, “Unleashed,” next week.

Kuenssberg previously examined his government in the Panorama episode “Partygate: Inside the Storm” and looked back at the final Conservative years in a three-part BBC Two series called “Laura Kuenssberg: State of Chaos.”

Kuenssberg wrote in a post on Wednesday evening This of course means that it is not right to continue the interview.

“It is very frustrating and there is no point in pretending it is anything other than embarrassing and disappointing as there are many important questions that need to be asked.” But red faces aside, honesty is the best policy. See you on Sunday.”

A BBC spokesman reportedly said the inadvertent action had made the interview “untenable” and that both the BBC and Johnson’s team had agreed to cancel the interview.

A spokesman for Johnson declined to comment.
