BORIS Johnson commands an imposing lead over his Tory rivals in the race for the keys to No 10, a YouGov poll has revealed.

The study, conducted for the Times, found that Johnson is the preferred choice of 39% of party members.

To be selected as the Conservative leader, the former foreign secretary would need to finish in the top two in a ballot by MPs. The ultimate victor would be decided via a vote by all Tory members.

Johnson’s closest challenger is former Brexit secretary Dominic Raab, who sits in distant second on 13%.

The poll also put Johnson in front of Raab in the event of a head-to-head contest, winning with 59% of the vote.

Other leadership hopefuls Michael Gove and Sajid Javid shared third place, with each being first choice among 9% of members.

Also tied were Defence Secretary Penny Mordaunt and Leader of the House of Commons Andrea Leadsom, who both polled at 5%.

Newly installed International Development Secretary Rory Stewart drew 4% of the votes, while Health Secretary Matt Hancock was only named as the preferred successor to Theresa May by 1% of respondents.

Although the research found that 49% of Tory Leave voters would back Johnson, a mere 10% of pro-EU members would support him and, overall, 31% felt that he would make a “poor leader”.

Asked at a business event in Manchester last Thursday if he would be a candidate in the leadership contest, the former foreign secretary replied: “Of course I’m going to go for it.

“I don’t think that is any particular secret to anybody. But you know there is no vacancy at present.”

Johnson also hit out at May for her handling of Brexit. “I do think there’s been a real lack of grip and dynamism in the way we approached these talks [with the EU],” he said.

“We’ve failed over the last three years to put forward a convincing narrative about how we can make sense of Brexit and how to exploit the opportunities of Brexit.”

The Daily Mail reported that a “Stop Boris” campaign within Tory ranks had already swung into action in an attempt to hamstring the MP’s prime ministerial ambitions.

The newspaper reported that one minister who was part of the campaign said that the move against Johnson had already begun to gain momentum.

“Boris cannot form a government, certainly not on a no-deal platform and probably not on any other.

“There are at least a dozen people on our side, me included, who would be prepared to vote against him on the Queen’s Speech,” the unnamed minister said.

“Even with the DUP on board, that is the majority gone. Then we are straight into an election.”

Another minister commented: “Boris is extremely popular with the members, but the situation is the opposite among his colleagues at Westminster.’’

First Minister Nicola Sturgeon said, in no uncertain terms that he was a “charlatan” and that the notion of Johnson as prime minister would “horrify” Scots.

Boris Johnson, the guy who misled people in the Brexit vote, the guy who has only ever put his own interests first as far as I can see – a complete and utter charlatan in my opinion,” she said during the SNP’s EU election manifesto launch in Glasgow on Friday last week.

“The prospect of him becoming Prime Minister of the United Kingdom is, I think, one that will horrify many people across Scotland.”
