An eyewitness to a shooting in Birstall, which left Labour MP Jo Cox dead, says he saw a man holding a gun and shouting "Britain first or put Britain first".

Clarke Rothwell told the BBC's Ed Thomas that he heard women screaming and a bang.

Jo Cox, 41, Labour MP for Batley and Spen, was left bleeding on the ground after the attack in West Yorkshire. A 52-year-old man was arrested nearby.
