In other comments made in the interview, Mr Blair said being Prime Minister is “the only job I can think of in which the importance of what you’re doing is so immense and the requirement of experience for doing it is so nugatory”.
Mr Blair then compared taking on the role of Prime Minister to a fan being appointed as manager of Manchester United.
He told the BBC: “The first job I ever had in government was prime minister.
“I use the analogy of a football team.
“If you’re looking for the new coach of Manchester United and ‘I tell you what we’re going to find the most enthusiastic and persuasive fan we can find and put in him charge of the team’.
“People would say you’re insane.”
