Rory Stewart is the only leadership hopeful talking sense, according to former Tory MP and former Attorney General Dominic Grieve.
Mr Grieve, who supports a second referendum, told talkRADIO’s Julia Hartley-Brewer: “[Rory Stewart] is the only candidate who is actually saying anything sensible about how Brexit is going to be carried out.
“The other candidates are all arguing they are going to eyeball the EU, find a deal or leave on October 31. That in my mind is a fantasy that is not going to happen.
“That is the point that Rory has been making throughout. To that extent, he is the only candidate who is talking sense.”
Mr Stewart is one of six candidates for the Tory leadership, including Sajid Javid, Jeremy Hunt, Michael Gove, Boris Johnson and Dominic Raab.
Referring to what he considers to be Boris Johnson's unsuitability for the role he added: “He is an attractive communicator but appears to have absolutely no content to what he has to say.
“He avoids debate and is happy to be thoroughly inconsistent provided it gets him what he wants.
“I accept that my party is deeply divided on the issue of Brexit. I, and a number of others, take a different view than Rory on its desirability, which is why I have called for a second referendum,” he said.
“I believe it still remains a viable option for resolving this issue one way or another. In the meantime, the best leader to support is one that is telling the truth, even if some of the policies that he is advocating are not totally in keeping with my own views.”
He added: “A lot of the other candidates are simply inventing a set of facts on which to base their policies.”
