Londoner Dwayne Fields sets sights on South Pole

Londoner Dwayne Fields hoped to challenge stereotypes when he completed an expedition to the North Pole, in 2010.

Now, the 29-year-old - who was once involved in a street shooting in Hackney - is hoping to walk to the South Pole.

He told BBC Breakfast why he has chosen to take up the challenge, even though he does not even like the cold.
