Intruder prompts review of security at Downing Street

SECURITY at the British Prime Minister’s residence was under review last night after an intruder armed with a large kitchen knife managed to climb into a secure area outside Downing Street.

Police officers had to overpower and arrest the man after he scaled a six-foot high set of iron railings to the rear of the Whitehall address.

Tony Blair is understood to have been in at the time, but Scotland Yard insisted there was never any threat to his safety.
