Mr Rees-Mogg, who is backing the former London mayor to be the next Tory leader, said for neighbours to record a row between Mr Johnson and his girlfriend and send it to a newspaper is “absolutely dreadful”. Boris Johnson has been at the centre of media attention after neighbours called the police to his girlfriend’s flat following a noisy late-night argument over the weekend.
The prominent Brexiteer told LBC: “I think it’s absolutely dreadful.
“I think the idea that snooping neighbours are recording what is going on for political advantage and then Class War protesters are coming to politicians’ front doors – which happened to me as well – is not a good place for politics to be.
“I think the politicians should feel safe and unmolested in their own homes. I don’t think that is an unreasonable thing to ask for.”
On Saturday night, the neighbour who rang the Metropolitan Police Force, went public to deny suggestions that his recording of the row had been leaked to Left-wing Remainer newspaper The Guardian with political intent.
Neighbour Tom Penn said the allegations were “bizarre and fictitious” and claimed the row “was loud enough and angry enough that I felt frightened and concerned for the welfare of those involved”.
Mr Penn, who supported Remain in the 2016 Brexit referendum, said he contacted the paper because he felt it was of “important public interest”.
But Mr Rees-Mogg hit out at the neighbours and said the decision to go to a newspaper and report the incident is “not attractive”.
The Brexiteer backbencher blasted: “The aggression of the hard left is really appalling and not how British politics has normally been carried out.
“And snoopers are always unattractive, Corbynista curtain twitchers are not attractive.”
Mr Rees-Mogg ridiculed the decision to record the row and said it was “all very unsavoury”.
He added: “Who reaches first of all for the mobile telephone to record it and then send it off to the Guardian. That’s a snooper.”
Mr Rees-Mogg also branded the newspaper “hypocritical lefties”, adding: “We should know that. It’s ‘do as I say and not as I do’. The Guardian should be ashamed of the way it has behaved in dealing with this sort of person.
“But I think for newspapers to think neighbours recording through the wall, I mean, you have this vision of them putting a glass next to the wall with their mobile, how long have they been doing that? Were they doing it day in and day out just in case they might catch a snippet of conversation that they can pass onto a newspaper?
“And who knows how to get in touch with newspapers as quickly as this?”
The Tory leadership frontrunner has so far refused to discuss the incident at the south London flat owned by his girlfriend Carrie Symonds in the early hours of Friday morning – insisting the party faithful did not want “to hear about that kind of thing”.
Mr Rees-Mogg support the former Foreign Secretary’s decisions and said: “Once you start saying ‘I am going to answer these questions’, then every question is opened up.”
