Armstrong quits Livestrong cancer charity

Former cyclist Lance Armstrong has today stepped down as chairman of the Livestrong cancer-fighting charity.

Last week, the US Anti-Doping Agency released a detailed report stating Armstrong had led the most "sophisticated and successful" doping programme that sport has ever seen, an allegation he continues to deny.

Armstrong made the decision to hand over the chairmanship of Livestrong to vice-chairman Jeff Garvey “to spare the foundation any negative effects as a result of controversy surrounding my cycling career”.

Nike will continue to support Livestrong but have terminated their contract with Armstrong “due to the seemingly insurmountable evidence that Lance Armstrong participated in doping and misled Nike for more than a decade”.
