Bradley Wiggins calls for bike helmet law
Olympic Gold medal winner Bradley Wiggins has called for new legislation to make it compulsory for cyclists to wear helmets, after a man died in a crash near the Olympic Park.
He was asked for his views on the safety of London's roads after the man was hit by an Olympic bus on Wednesday.
It has not been revealed whether the victim was wearing a helmet, but Wiggins said forcing cyclists to take precautions would make the roads safer.
