London - A British adventurer has died after suffering exhaustion and dehydration while attempting to cross the Antarctic alone.
Former army officer Henry Worsley was just 48km from the end of the almost 1 600km trek when he called for help and was airlifted off the ice on Friday.
His family said on Monday that Worsley died "following complete organ failure" at a clinic in Punta Arenas, Chile.
The 55-year-old Worsley covered more than 1 400km miles in 71 days, pulling supplies on a sled, while attempting to complete Ernest Shackleton's unfinished South Pole expedition of a century ago.
Worsley's wife Joanna said the expedition had raised more than $140 000 for wounded troops.
Prince William, patron of the expedition, said he and brother Prince Harry had lost a friend.
