Britain's leadership contest was rocked on Saturday by reports that police were called to a late-night "row" between frontrunner Boris Johnson and his partner, just hours before campaigning opened to win over grassroots Conservatives.
The Guardian said officers were alerted early on Friday after a neighbour said there had been a loud altercation involving screams, shouts and bangs at the south London property, shortly after Johnson had secured his place in the final run-off to become prime minister.
The paper said late Friday Johnson's partner Carrie Symonds could be heard telling the former London mayor to "get off me" and "get out of my flat".
London's Metropolitan Police said it responded to a call from a local resident but that "all occupants of the address... were all safe and well".
Johnson, who is the runaway favourite to beat Jeremy Hunt, refused to answer questions on the issue during the first date of a month-long nationwide tour he is conducting with Hunt to win over Conservative members, who have the final say.
"I don't think people want to hear about that kind of thing," he told interviewer Iain Dale, to cheers from a friendly crowd at the first of 16 "hustings" -- where candidates field audience questions.
He instead tried to focus on his policies, saying "we need to get Brexit done" and promising to prepare Britain for a no deal exit from the EU, if a deal cannot be reached.
Whoever takes the Tory party leadership in the week beginning July 22 -- and therefore becomes prime minister -- will face the looming Brexit deadline of October 31.
But the race might ultimately turn into a popularity contest between Johnson -- pugnacious but affable with a tendency for gaffes -- and the more diplomatic, low-key Hunt.
The "row" was splashed across the front pages of most newspapers on Saturday, and while bookmakers were still betting for Johnson, pundits warned the incident could harm his chances.
"Much will depend on the next 24 hours and whether the audio said to have been recorded by a concerned neighbour emerges," said The Times newspaper.
"At the very least it will ensure a leadership race that had started to look like a formality might in fact be something of more consequence."
Fearing Farage
After the MPs whittled down the original field of 13, it is now up to the 160,000 or so paid-up Conservative members who select the centre-right party's next leader.
According to Times commentator Matthew Parris, the group comprises "classic shire Tories", as well as poorer urban workers who are anti-European and more populist in their views.
The winner will need to succeed where May failed in pushing a deal with the EU through parliament, or face the prospect of leaving without a deal, which MPs have warned could collapse the government and trigger a general election.
With arch-Brexiteer Nigel Farage's new Brexit Party ahead in the polls, Johnson is widely viewed as the one Conservative who could compete in the party's heartlands.
A poll for The Daily Telegraph -- the paper for which Johnson writes a column -- showed six out of 10 Brexit Party backers jumping over to the Conservatives should the man known simply as Boris take charge.
'Bottler'
Foreign minister Hunt launched an early attack on his rival, accusing him of ducking a television debate.
"This is supposed to be his finest hour ... but if you're going to hide away, that's not democracy," he wrote in Saturday's Daily Telegraph.
"Conservative Party members can only make that choice if you have a proper debate and you can't have that debate if one of the candidates is bottling all opportunities."
Both Johnson and Hunt have vowed to extract better terms from Brussels, something ruled out by European leaders, or walk away without any strings attached.
