Armstrong set to address doping allegations in Oprah interview

Lance Armstrong will break his silence over allegations of drug doping after it was announced he is to be interviewed by Oprah Winfrey next week.

The American was stripped of his seven Tour de France titles by the sport's governing body the International Cycling Union (UCI), following a report by the US Anti-Doping Agency which concluded the 41-year-old and his US Postal Service team had run "the most sophisticated, professionalised and successful doping programme that sport has ever seen".
