MPs on the House of Commons home affairs committee are threatening an unprecendented vote of no confidence in Keith Vaz if he refuses to resign as chairman when he meets them on Tuesday.

Mr Vaz is due to meet with the committee in the Commons to give his side of the story after tabloid claims that he paid male prostitutes for sex and offered to take poppers and pay for cocaine for them.

The meeting comes after Theresa May, the Prime Minister, put pressure on the Labour MP by saying that any decision to resign was one “for him to take”.
