Intruder with fake ID 'wandered round Parliament for 12 hours'

Security at UK Parliament's gates was breached last year by an intruder who flashed fake identification and wandered around the estate for 12 hours, it has been claimed.
The Sunday Telegraph said officers at Carriage Gates, where Pc Keith Palmer was stationed when he was stabbed by Khalid Masood in Wednesday's terror attack, were fooled by a 29-year-old who did not have security clearance.
