A charity for injured servicemen and women has been awarded £100,000 from a fund set up by the Duke and Duchess of Cambridge and Prince Harry.
Walking With The Wounded - which helps retrain injured military personnel for careers in civilian society - was given the grant by the Endeavour Fund for its 2013 South Pole Allied Challenge.
Harry, the expedition patron, announced last month that he will make the gruelling 210-mile trek across Antarctica this winter.
In 2011 the 28-year-old royal took part in a successful expedition to the North Pole and last year a five-man team of injured soldiers was forced to turn back on the slopes of Mount Everest amid treacherous conditions.
The Endeavour Fund was set up last year as part of William, Kate and Harry's Royal Foundation with the aim of enabling more wounded servicemen and women to take part in expeditions and sporting challenges. Their first grant was a £100,000 donation made to the charity Race2Recovery to compete in the off-road desert race the Dakar Rally.
Walking With The Wounded said its grant will be used to support the injured South Pole team members to undertake the expedition and raise further funds and awareness through television and consumer awareness.
The South Pole Allied Challenge will be a race of three teams of international wounded military personnel - all of whom sustained physical or mental injuries in the line of duty - across the coldest, driest and highest desert on the planet.
Harry will be in the UK's Team Glenfiddich and will compete against United States and Commonwealth teams.
Nick Booth, chief executive of The Royal Foundation, said: "The Endeavour Fund is delighted to partner with Walking With The Wounded on their most ambitious expedition to date. The Duke and Duchess of Cambridge and Prince Harry are all dedicated to helping our wounded undertake truly great adventures and sporting achievements as part of their recovery. The Walking With The Wounded South Pole Allied Challenge is a perfect demonstration of the tenacity and resolution of the inspirational men and women who serve both our nation and our allies."
During his current tour of the US, Harry started the first event of the Warrior Games and helped launch the Paralympic-style competition when he ignited a large symbolic flame during the Games's opening ceremony.
