British PM Cameron stopped by guard ?

A diligent guard deputed for Olympic security duty surprised Whitehall-headed British Prime Minister David Cameron Monday by asking him to show his papers.

Cameron, however, praised the squaddie for being “on his marks” as he walked to Downing Street after using the London Underground to visit the Olympic Park in Stratford.

The Tube was “pretty good”, Cameron told ITV London Tonight while adding: “I was stopped going down Whitehall by a soldier. I didn’t have my papers.”

“People said London would be gridlocked today and it wasn’t. The transport system has coped,” he added.

According to London Mayor Boris Johnson, organisers have turned off some of the Olympic road lanes reserved for bigwigs since officials are travelling by public transport.

Even International Olympic Committee president Jacques Rogge took the Docklands Light Railway instead of a car, he added.
