Male MPs no longer have to wear ties in the House of Commons, the Speaker has announced.

It has been long-standing convention in the chamber that male members must wear both a jacket and tie as part of a set of rules governing conduct and courtesy, John Bercow said.

But breaking from convention the Speaker, who has a reputation for shaking up the rules of Parliament, said he would still call an MP who wished to speak even if they were not wearing a tie.
