Whatever the royal family may think of his exploits in Las Vegas, many Britons can barely hide their support for Prince Harry, posting naked pictures of themselves online in tribute.

A Facebook group entitled “Support Prince Harry with a naked salute!” — featuring people posing in various states of undress saluting the third-in-line to the throne — has won 13,000 members and is still growing.

The group sprang up after Harry, 27, was photographed naked with a mystery woman during a game of “strip billiards” in a Las Vegas hotel suite.

The online show of support for Harry came as it was announced that he will be the patron of a charity race to the South Pole between three teams of wounded servicemen from around the world.

Harry, who last year joined a group of injured soldiers as they trekked to the North Pole, is supporting the Walking With The Wounded South Pole Allied Challenge 2013.

Troops from Britain, the US and the Commonwealth who suffered physical or cognitive injuries while serving will take part in the four-week expedition next year.
