2.40pm update: Fallon hints at real reason Johnson refuses to go into detail on Brexit
Senior Tory Michael Fallon said the Tory leadership hopeful wants flexibility in Brexit talks with the EU.
Speaking on the BBC’s Newsnight, Mr Fallon said: “There is a very good reason why Boris hasn’t gone into the precise detail of the negotiation that he would like to start with the EU.
“Of course, he wants to maintain the maximum flexibility as you go into those negotiations. A lot of this will have to be looked at again.
“The agreement that was negotiated by the current Cabinet, including Jeremy Hunt, has failed.
“It failed to get through Parliament and we have been becalmed since Christmas.
“We have to look at this again and these issues like the backstop and the future customs relationship with the EU have to be examined again both here and in Brussels and some of the other important capitals like Dublin.”

Tim Martin said: “Boris Johnson would be a good Prime Minister.
“He’s been elected Mayor of London twice, which is a multicultural city, and I think it’s very important for the country to have a Brexiteer prime minister to take advantage of all the opportunities of Brexit and who believes in Brexit.
“He’s a hard worker, he’s charismatic, he’s got strong liberal views. I think he’d make a good prime minister.”

“But you know — the president has his style and his approach.”
