Compulsory bike helmets debate

Politicians and cyclists have entered a debate about wearing safety helmets, after gold medal winner Bradley Wiggins suggested they should be made compulsory.

His comments follow the death of a cyclist who collided with an Olympic shuttle bus.

Wiggins said a lot of London's bike riders don't help themselves by the way they behave on the road.
