Mr Johnson refused to answer questions on his private life six times, following the visit by police to the home of his girlfriend Carrie Symonds. And rival Jeremy Hunt has made good progress in the polls after the late-night incident in Camberwell. And Boris was further hit this morning following news of a plot he could be replaced as prime minister after just one day in Number 10.
Yesterday marked the first of 16 hustings between the pair as the candidates faced Tory members in Birmingham.
They will head south for the next grilling on Thursday.
In the meantime, Team Boris will look to regain the initiative after latest polls showed Mr Hunt would make the best prime minister according to a survey of the general population.
Mr Hunt won by 32 precent compared to Mr Johnson’s 29 percent – a swing of 11 points following the police call.
But the Survation poll said Boris still has an 11 point lead over Conservative voters when asked who would be best in Number 10.
Last night, aides of Boris claimed the call to police was a left-wing “stitch up” by neighbours. However, the neighbours say they had genuine concerns over “safety and welfare”.

11.45am: Tory Party chairman warned over ‘bullying’ over Boris backing
Shock claims have been made to Tory Party chairman Brandon Lewis that MPs were “bullied” into backing Boris Johnson.
The allegations came in an email sent to the Conservative chief.
David Moris, MP for Morecambe and Lunesdale, wrote the email which claims one MP received a phone call from his local association chairman threatening to pass a motion of no confidence in him if he did not vote for Mr Johnson.
Mr Norris wrote: “This is intimidatory behaviour. These are very serious tactics and could lead to criminal prosecutions.”
11.10am: Boris Johnson’s girlfriend ‘too scared’ to return home
Boris Johnson’s partner is said to be too frightened to return home after neighbours called police to the South London flat the couple share.
An insider said: “As far as Carrie is concerned this is a stitch-up.
“It was a row like lots of couples have at the end of a demanding day but suddenly they found the police on their doorstep.”
And Miss Symonds told friends she is now “too sccared” to return.
10.05am: Russian spies behind Boris assassination plot story?
Russian spies may be behind false online stories claiming “radical opponents of Brexit” were plotting to kill Boris Johnson.
The Atlantic Council’s digital research unit made the claim after studying suspended Facebook accounts originating from Russia.
They shared a fake letter claiming to be from the Spanish foreign minister outlining the astonishing plot.
9.20am: Plot to oust Boris Johnson after just one day
Boris Johnson could be axed as prime minister after one day in office, over fears he is a security risk.
The shock claim is in the Sunday Times, which reports chief whip Julian Smith of teling Johnson’s campaign team he could lose a vote of confidence in 24 hours.
It comes as two Tory MPs are on a high risk list to defect, thereby destroying the party’s majority.
Mr Smith revealed Labour MPs are on a “hard three-line whip” for the day after Mr Johnson’s election to back Jeremy Corbyn’s no confidence motion.
