BBC Sports Personality 2011: Bob Champion wins Helen Rollason award

Bob Champion, the 1981 Grand National-winning jockey, wins the Helen Rollason award at the BBC Sports Personality of the Year awards in Salford.

Champion fought cancer to win the world's most famous steeplechase at Aintree on injury-plagued Aldaniti in 1981, and has been a tireless fundraiser ever since.
