David Beckham, Sainsbury's Active Kids ambassador, takes a trip down memory lane as he returns to his old primary school in East London. It's the first time he has been back to Chase Lane Primary school since leaving 30 years ago. He makes a surprise appearance in assembly, meets the school football team who are off to play at Wembley, joins in at lunch time and catches up with lots of very excited kids.

Chase Lane primary school has been collecting Active Kids vouchers since 2006 and is one of the 51,000 organisations registered to the scheme.
