The ComRes survey on behalf of The Sunday Telegraph, found 61 percent favoured Mr Johnson compared to just 39 percent for Mr Hunt. Mr Johnson is still the favourite amongst bookmakers for the position, but most of his odds have shortened after police were called to the home of his girlfriend Carrie Symonds following a reported row. The police left satisfied no further action was required and Mr Johnson insisted in his hustings in Birmingham that this was a private matter.
Journalist Iain Dale was booed when he asked the leading Brexiteer to explain what happened, though Mr Johnson urged supporters not to.
The poll was conducted over Friday and Saturday as news of the incident broke in the national press.
Even more councillors – 88 percent of those polled – said it was likely Mr Johnson would emerge as the winner of the contest.
Some 510 councillors took part in this poll, though this is just under seven percent of the 7,480 Tory councillors nationwide.

With suggestions Labour leader Jeremy Corbyn could force a no-confidence vote, 71 percent of those surveyed felt it was Mr Johnson who was in the best position to defeat the Leader of the Opposition.
Mr Johnson has had experience in taking on the hard left of the Labour party before.
In 2008 he defeated Ken Livingstone in the London mayoral election by a margin of seven points.
Four years later he retained the mayoralty with a three point margin.
However, in 2016, his fellow Brexiteer Zac Goldsmith was decisively defeated by Labour’s Sadiq Khan.
The winner of the Tory leadership contest will be announced in the week beginning July 22nd.

Theresa May will remain as Prime Minister and acting party leader until her successor is announced.
