Labour MPs have been forced to call in the police over death threats in the last 48 hours after they refused to back Jeremy Corbyn, The Telegraph has learnt.
Vicky Foxcroft, a Labour whip, received a call to her constituency office which said: “If she doesn’t support Corbyn I will come down to the office and kick the f*** out of you.”
Another MP who resigned over Mr Corbyn’s leadership has received an email naming their child and threatening to kill them. Police have been passed the message and are now investigating.
Lucy Powell, the former shadow education secretary, received a message telling her to kill herself after announcing she would leave the frontbench over frustrations with the leadership.
It was among a string of messages laden with expletives and personal abuse which have been passed onto police.
A fourth Labour MP said they had become so concerned with the torrent of online abuse that they have forwarded the messages to police, while scores of others raised concerns.
The rhetoric of Mr Corbyn’s supporters has been criticised after John McDonnell initially encouraged activists to protest MPs – but later made clear he did not condone constituency office protests.
The spike in hostile messages was compared to the surge in the run-up to the Syrian air strikes vote last year, which led to a new security package for MPs being issued amid concerns over safety.
Politicians and staff were said to be in tears over the abuse comes just weeks after the brutal murder of Jo Cox, the Labour MP for Batley and Spen who was shot and stabbed in her constituency.
A Labour source said: “Women MPs have been subjected to the most vile stuff – we’re going to rape you, kill you. There have been people in tears today.”
The call to Ms Foxcroft’s constituency office in Lewisham, south London, was made on Tuesday during which a man called demanded to know whether she backed Mr Corbyn. She is a whip and therefore remains neutral.
When the case worker – who is in his twenties – did not reveal her position the man became agitated, promised to “kick the f***” out of staff and said he was heading to the office.
Ms Foxcroft told The Telegraph: “As an MP, your skin gets pretty thick, pretty quickly. But when John McDonnell calls on Momentum activists to campaign against their MP’s, it doesn’t take that much for people to feel like they should take things into their own hands.
“My staff work hard to provide support for hundreds of my constituents. They don’t need this level of abuse and threatening behaviour. Understandably, it has been quite a worrying time for them in recent weeks. I sincerely hope this is the last of the aggression they will have to receive.”
A Labour source said that Mr McDonnell had told activists not to protest outside Labour constituency offices and “could not have been clearer” in his opposition.
MPs on all sides of Labour’s party split have repeatedly spoken out against online abuse against politicians.
