Former Armstrong team-mate describes 'systematic' doping

Lance Armstrong's former team-mate, Tyler Hamilton, has described an alleged systematic programme of doping in the US Postal team in which the seven-time Tour de France winner played a leading role.

Hamilton was speaking to the CBS programme '60 Minutes', portions of which had been aired on Thursday and Friday where he described how he had seen Armstrong take the blood-booster EPO and testosterone as well as having a blood transfusion.
