Meet Britain's least-known world number one: Kat Driscoll

Trampolinist Kat Driscoll has a claim to the title of Britain's least-known world number one in any Olympic sport.

Seven years have passed since Driscoll, 25, moved from Kent to the town of Washington, in Tyne and Wear, where she has been preparing for this week's World Championships in Birmingham and next year's Olympic Games.

Driscoll introduces BBC Sport to her teenage training partners who, she says, provide constant entertainment and help to maintain her love for a sport at which she is the best in the world.
