Lance Armstrong confession: Sir Bradley Wiggins "sad & angry"

Tour de France winner Sir Bradley Wiggins describes his feelings of "sadness and anger" at watching Lance Armstrong admit to doping throughout his career.

The Olympic time trial winner was "a fan" of Armstrong but now feels "cheated" and says the revelations are "sad for the sport".

Wiggins reveals that he watched the Oprah Winfrey interview with his 7-year-old son and says he's "incredibly proud" that he will never have to make such an admission.
