Prince Harry takes an Arctic dip - the BBC's Frank Gardner reports
Prince Harry's arrived in the Arctic to join four wounded ex-soldiers on their trek to the North Pole.
The group is hoping to become the first disabled team to get to the North Pole unaided, while raising £2million to help other injured ex-servicepeople.
Harry's been busy training for the expedition, which included jumping into the icy cold Arctic Ocean!
He's joining for the first five days of the gruelling 200-mile walk, which should take about four weeks to do.
Prince Harry said: "This extraordinary expedition will raise awareness of the debt that this country owes to those it sends off to fight. These men and women have given so much."
