Tory Brexiteer Jacob Rees-Mogg has brushed off a protest by anarchist demonstrators who harangued him and his young children outside his London home.

Video footage posted online by Class War shows veteran protester Ian Bone telling one of the MP’s sons: “Your daddy’s a totally horrible person, lots of people don’t like your daddy, do you know that?”

Downing Street condemned the protesters’ actions, describing them as “completely unacceptable”.

“No elected member or their family should be subjected to intimidation or abuse in that way,” the Prime Minister’s official spokesman said.

However the MP sought to play down the incident, insisting his children were “absolutely fine”, despite the barracking.

“I wouldn’t get too excited about it. It was a few anarchists who turned up and it wasn’t very well organised. It wasn’t terribly serious,” he told LBC radio.

“We are a free country. They weren’t violent. They aren’t admirers of mine. I am in public life and not everybody is going to like me. That is a reality of public life.

“I’d have preferred it if it hadn’t happened but I don’t want to get it out of perspective. I think much worse things happen to many other people.”

The online footage shows a small group of protesters confronting Mr Rees-Mogg and his wife and four of their six children on the pavement outside their London home, while a policeman looks on.

Mr Bone is seen taunting them, accusing them of failing to pay the family’s nanny, Veronica Crook, properly.

“Poor Nanny Crook who looks after you and wipes your bottom, she doesn’t get enough money every week. Daddy doesn’t care,” he says.

He then challenges Ms Crook directly to say, how much she is paid. She replies: “I don’t need to tell that. All I can tell you is I’m very happy.”

Mr Bone dismissed criticisms of the group’s actions, claiming Mr Rees-Mogg had brought his family out after they had confronted him in the street.

“They are hardly the most stinging examples of invective are they? He is a feudalist landlord scum of the worst kind,” he told the Press Association.

He said the protest had attracted so much publicity, they planned to make it a regular event.

“We are going to be back same time every week,” he said.
