A wristband worn by British tennis star Andy Murray and donated for auction by the Duchess of Cornwall has raised more than £2,000 for charity.

Camilla, who is a passionate tennis fan, received the sweaty memento after watching Murray in action at Wimbledon during the tournament's first week.

Murray chose the good cause which benefited from the online auction - the Animal Care Trust, the Royal Veterinary College's registered charity.

Camilla has been its patron for the past ten years and has a keen interest in animal welfare.

The tennis star, who lost his Wimbledon semi-final match to Roger Federer, had signed the wristband, which was put up for sale on the online auction site eBay on Friday.

It attracted 45 bids and was sold to an anonymous bidder for £2,100 when the sale ended at lunchtime.

The eBay listing for the item featured an image of the Duchess in the stands at number one court holding the tennis souvenir.

An official explanation of the auction item posted on its sale page said: ''The wristband landed with Her Royal Highness after being caught by chairman of the All England Lawn Tennis and Croquet Club, Mr Philip Brook.

''The humorous exchange was captured by photographers and TV crews and the Duchess has decided to put it on eBay for fans all over the world in the hope that it will raise money for charity."
