Speaking openly about Brexit for the first time since leaving Downing Street three years ago, Mr Cameron has said he wants Mr Johnson “to succeed” but does not have faith in his approach to having the Leave process. The former Conservative leader has stuck to the sidelines of politics since quitting No10 in the aftermath of the EU referendum.
But now, one week ahead of the release of his memoirs, Mr Cameron has given an insight into his opinion on his successor, the 2016 Leave and campaign and the state of British politics.
Despite complementing Mr Johnson on his leadership qualities, Mr Cameron has used his first major interview since leaving the political stage to criticise the Brexiteer’s approach to leaving the EU.
Speaking to The Times, the former Conservative leader said: “I want him to succeed. I worked with him well, as I say in the book.
“I also say that he was a capable mayor. He was easy to work with. I thought he was very talented. I wanted him in my government.
“We’ve had issues. Even before Brexit there were sometimes tensions and disagreements but, on the whole, we’ve got on well. And I want him to succeed.
“Look, he’s got a very clear strategy and plan.
“It’s, you know, not the approach that I would have taken, but I want him to succeed.”
The former Tory leader also used the interview to take aim at Mr Johnson's decision to prorogue Parliament in an attempt to stop MPs from undermining his Brexit plan.
The Prime Minister suspended Parliament on Monday evening until October 14.
The Government has insisted the prorogation is only taking place to allow new legislation to be presented to Parliament.
But critics have accused No10 of using the suspension to try and limit MPs' ability to scrutinise the Government's Brexit plan.
Joining those who have attacked Mr Johnson for his decision, he said: "You’ve got to find some way of unblocking the blockage. I think there are certain things you shouldn’t do to unblock the blockage.
"I think proroguing parliament – pretending it doesn’t exist – I think that would be a bad thing.”
