THE Range Rover used by the Duke and Duchess of Cambridge to carry their son George home after his birth three years ago is being sold at auction for charity.

The car is being auctioned online through CharityStars.com to raise money for charities Sun Screen IT and Stand Down.

Sun Screen IT donates IT equipment for schools, hospitals and orphanages in developing nations and Stand Down is a military mental health charity, which provides online counselling and support to the armed forces and their families.

The Range Rover Vogue SE SDV8, which was Prince William and Catherine's personal vehicle, is expected to sell for at least £150,000 - nearly double its reserve price.

It was supplied originally to The Duke and Duchess of Cambridge via Land Rover's VIP Department and is fitted with many additional features and is fitted with a front console fridge and a surround view camera system. The car has 31,000 miles on the clock.

It became one of the most photographed vehicles in the world when the royal couple used it to transport Prince George home from St Mary's hospital in London in July, 2013.

CharityStars.com was founded in 2013 and since launching more than 1,000 celebrities including Andy Murray, Lionel Messi, Jessie J, Joss Stone, David Coulthard and Sir Bobby Charlton have worked with the organisation, raising more than £2.5 million.

Robert Robinson, CharityStars.com managing director, said: "We are delighted to be hosting this auction and hope to take it to the next level in digital fundraising by raising a phenomenal amount of money for two incredible charities."
