**Details of the first unaided trek to the North Pole by disabled servicemen are to be announced by Prince Harry.**The royal, who is patron of the Walking With the Wounded charity organising the four-week trek, will launch the event at The Rifles Club in west London.
The amputees, who lost limbs in the line of duty, will try to reach the geographic North Pole from Siberia.
They will haul heavy sledges over 300 miles (483km) across the frozen Arctic Ocean in temperatures down to -50C.
Organisers say next year’s trek will raise money to help rehabilitate wounded service personnel back into the workplace.
‘Tenacity and courage’
Expert guides, including adventurers Henry Cookson and Inge Solheim, will accompany the amputees through tough terrain and hazards, including aggressive polar bears.
BBC security correspondent Frank Gardner said candidates are still being whittled down for the record attempt in April next year.
He said those on the final shortlist will undertake their first Arctic ice training in May.
The 25-year-old prince said: "This polar adventure will exemplify the tenacity and courage of those who serve in uniform.
“Walking With The Wounded promises to be remarkable. I salute the team walking to the North Pole in early 2011 and I urge the public to get behind them.”
Harry, who has served in Afghanistan, has been training to become a pilot with the Army Air Corps for more than a year.
