The car veered across a cycle lane and smashed into parliament’s perimeter wall outside New Palace Yard. A man in black is said to have jumped out of the car and rushed through the gates into New Palace Yard where he attacked two yellow-jacketed policeman at the security gates. One officer was repeatedly stabbed and fell to the ground. The attacker turned to run but was challenged and shot several times by plain-clothes officers.
