Lance Armstrong: Usada reveals doping evidence

Cycling legend Lance Armstrong's team ran "the deepest, most sophisticated and successful doping programme the sport has ever seen", according to the United States Anti-Doping Agency (Usada).

In its report, Usada said Armstrong, 41, "engaged in serial cheating" associated with doping.

The report contains testimony from 11 of his ex-US Postal Service team-mates.
