British members of parliament have been advised to take taxis or travel home together to avoid the risk of abuse over Brexit.

Lindsay Hoyle, a deputy speaker of the House of Commons, wrote to all MPs saying the Metropolitan Police has been “left in no doubt” that they must ensure “Members of Parliament can vote in Parliament without fear.”

Hoyle, a Labour MP since 2010, wrote: “Personally, I have never felt this level of tension during my time in the House and I am aware that other colleagues feel the same.

“Many colleagues have already been subject to widely publicised abuse and intimidation.”

He advised MPs to take “simple steps to improve our personal safety" such as traveling home by taxi or with colleagues, as "tensions and emotions are running at an all-time high."

Labour MP Lloyd Russell-Moyle said on Thursday that a man had tried to assault him and had branded MPs "traitors."

Also on Thursday, Tobias Ellwood, a Conservative MP and defense minister, tweeted a letter he was sent, threatening him and pledging to "bring London to its f***ing knees."

John Bercow, the speaker of the House of Commons, on Thursday told MPs they are not "traitors" and each must do "what he or she thinks is right," the day after Theresa May blamed parliament for the Brexit delay.

The prime minister said on Wednesday: "You the public have had enough ... I agree, I am on your side." She added: "You asked us to get on with it, and that is what I am determined to do." A longer delay would only serve to "give more time for politicians to argue," she said, warning that the public is fast losing patience with "political games” in Westminster.

Bercow on Thursday sought to reassure MPs that they have done nothing wrong.

"None of you is a traitor. All of you are doing your best," he said. "I believe passionately in the institution of parliament, in the rights of members of this house, and in their commitment to their duty ... The sole duty of every member of parliament is to do what he or she thinks is right."
