London (CNN) British Members of Parliament have been advised to take taxis home, over fears that they could be attacked by members of the public over the handling of Brexit.

In an email obtained by CNN, Deputy Speaker of the House of Commons Lindsay Hoyle wrote to lawmakers explaining that the Serjeant at Arms -- who is responsible for security -- had organized for black cabs to collect MPs from within the grounds of parliament in Westminster, central London.

"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," Hoyle wrote. "Many colleagues have already been subject to widely publicized abuse and intimidation."

The deputy speaker suggested that lawmakers "take simple steps to improve our personal safety by traveling home from the House by taxi or with colleagues in the coming days."
