First Lady Michelle Obama has urged youngsters to stay healthy and active at an event at the US Ambassador's residence in London.

Around 1,000 American and British children attended "Let's Move!" taking part in sporting activities and meeting US and UK athletes, including David Beckham.

Mrs Obama scored against an unconventional goalkeeper, SpongeBob SquarePants, but appeared less adept at tennis and tug of war.
