Stalker throwing punches in sleep

GB boxer Tom Stalker says he is so keen to achieve Olympic gold he wakes up fighting in the middle of the night.

The light-welterweight is ranked number one at 64kg and has already qualified for the Games.

On Monday, Nicola Adams, Natasha Jonas and Savannah Marshall also secured their spots in the GB squad, as women's boxing makes its Olympic debut this summer.
