The former prime minister was due to talk to Laura Kuenssberg about his new memoir, with a highly publicised special programme due to air on Thursday evening.
The BBC has cancelled an interview with Boris Johnson after Laura Kuenssberg accidentally sent the former prime minister her briefing notes.
Kuenssberg, who presents the broadcaster’s Sunday politics show, said “there’s no point pretending it’s anything other than embarrassing and disappointing”.
Revealing the error on X, she said she had been preparing to interview Mr Johnson on Thursday and “by mistake I sent our briefing notes to him in a message meant for my team”.
“That obviously means it’s not right for the interview to go ahead,” she added.
The former BBC political editor said it was “frustrating” and there are “plenty of important questions to be asked”.
“But red faces aside, honesty is the best policy,” Kuenssberg added.
