MPs have said they are living in "genuine fear" after they received death threats and abuse during the general election campaign.
Theresa May has ordered a Number 10 policy unit review into the issue, inviting MPs to share details of their experiences as “evidence gathering.”
Cabinet held a discussion earlier this week about intimidating electoral practises after the issue was raised by Andrea Leadsom, leader of the House of Commons.
Former Conservative MP Byron Davies, 64, received two death threats online a few weeks before the election in which he lost his Gower seat.
He was threatened with being “strung up” if he showed his face again in a particular area, he told The Sunday Telegraph.
A female candidate in her 30s, who was running for a safe Labour seat, said attacks on social media left her feeling “genuine fear”.
“It has made me think whether I really want to be an MP,” she said.
Nigel Evans MP described a “new low in campaigning” after he was screamed at by a man in New Inn pub in Clitheroe on St George’s day.
“You are a terrorist, child murderer, go back to Swansea, you are not welcome here,” he was told.
Earlier this week Sarah Wollaston, MP for Totnes in Devon, told The Guardian she felt she was being “forced out of town” by abusive words on her office building.
But she insisted Labour MPs had suffered worse abuse.
Twitter trolls have been convicted for death threats to Angela Eagle, Stella Creasy and Luciana Berger.
Nimco Ali, a candidate for the Women’s Equality party, was sent a letter threatening her life and signed ‘Jo Cox’.
The first Conservative MP to speak out was 61-year-old widow Sheryll Murray, who talked at PMQs two weeks ago about receiving death threats and having her door urinated on.
“Hardly kinder, gentler politics,” she said of the behaviour.
Ms May said she was “determined to stamp it out” and highlighted the disproportionate number of attacks on female MPs.
