The approach on Jacob Rees-Mogg's children by protestors was "a really, really scummy thing to do" Neil Coyle MP has said.
The MP told Julia Hartley-Brewer he was "horrified" to see lead protestor, Ian Bone, shout to the Rees-Mogg children that their "Daddy is a horrible person".
"If you really disagree with him and it's a protest about him why not have a go at him? Why not discuss the ideas or argue with him? Instead they chose to shout at the kids and I think that says a lot about the nature of the people involved," he said.

The politician also revealed he had sent a private message to Rees-Mogg after the protest which occurred outside his home in Westminster.
"Jacob Rees-Mogg is stuck in a time warp from a different century and I can't think of a single thing we agree on, but I did send a message to him yesterday to say how horrified I was to see it. I thought it was a really, really scummy thing to do.

"What worries me is that the level of coverage of this will actually appeal to some of the weirder and cranks at both eneds of the political spectrum who just want to be noticed. They'll feel it almost endorses their protest by having this level of coverage. And that's why many people are more nervous about entering politics or being in public life.
"The reassuring thing should be that 99.9 per cent of the population would agree that it's completely unacceptable to shout at children because of the views, opinions or politics of their parents. It's a no go area."
'Knickers in a twist'
A number of MPs have condemned the actions of the protestors on Twitter, including Stella Creasey MP, who said targeting the children was "sick" and "beyond the pale".
A post on the Facebook page of anarchist group Class War, who were behind the protest, read: "Right you lot out there who are all getting yer knickers in a twist over the Rees Mogg visit: He wheeled his children, Stepford Wife and Nanny out AFTER we arrived.
"He was the one who brought them all out. Desperate attempt by him to use his kids in a fairly sick way. Tell us who's the bully there then…"
