An entire generation of cyclists doped, says Jamie Staff

Olympic gold medallist and USA cycling's track sprint coach Jamie Staff tells BBC South East Today that an entire generation was probably involved in doping.

Staff's comments came as Lance Armstrong was stripped of his seven Tour de France titles by the sport's governing body, the International Cycling Union (UCI) on Monday.

The former BMX champion also said he believed Armstrong had been made a scapegoat following the revelations over drug-taking in the sport.
