House of Commons leader David Lidington has been giving an update on the situation in Westminster.
He told MPs that a “police officer has been stabbed” and that the “alleged assailant was shot by armed police”.
He added that there were “reports of further violent incidents in the vicinity of the Palace of Westminster.” The London Ambulance service said it had sent a number of crews to the scene.
Journalist Quentin Letts told the BBC:
We saw a thick set man in black clothes come through the gates into New Palace Yard and he was carrying what looked like a stick. He was challenged by one of the policemen in yellow and then one of them fell down and we could see the man moving his arm in such a way that he appeared to be stabbing the policeman.
The police called for help, which came very quickly and the man had moved perhaps 15 yards when two plain clothes guys with guns shouted at him – what seemed like it was a warning and he ignored it and they shot him two to three times and he fell.
