Adventurer Sir Ranulph Fiennes has told Daybreak that it took four years to get a permit to go to the Antarctic in the winter.
He said: "The Foreign Office don't let British subjects down there because there are no rescue facilities on an area bigger than China and India put together
"So if you need rescue you just don't get rescued."
- The name of the expedition is called 'The Coldest Journey'.
- The expedition will begin on 21 March 2013 at the winter equinox.
- It will take six months in total - crossing Antarctica to reach the Ross Sea and has taken 5 years to plan.
- Fiennes is aiming to travel 2,000 miles across the continent over six months, mostly in complete darkness and in temperatures approaching -90C.
- The SA Agulhas will take on board technical equipment and supplies including two 20-tonne tractors, two cabooses, scientific equipment, fuel sleds, specially heated clothing and Antarctic cold weather gear, and a variety of food supplies.
The veteran explorer Sir Ranulph Fiennes is to set off on his coldest challenge yet today - a journey across the heart of Antarctica during the winter.
