So the Police do have a sense of humour

Policemen at the Palace of Westminster are notorious for their mischievous sense of humour when it comes to dealing with tourists.

For example, they once nominated a camera-shy constable as the "official" PC to be photographed by visitors eager to be snapped with a British bobby.

But the latest wheeze takes the biscuit.

Apparently when tourists ask why Big Ben has been silenced for work on the famous bell, they are told: "Because it's going digital."
