Armstrong denies new drug allegations

Seven-time Tour de France champion Lance Armstrong has denied claims by former team-mate Tyler Hamilton that they took performance-enhancing drugs together.

Hamilton has accused seven-time Tour de France winner Armstrong of doping while insisting the majority of his fellow riders did likewise. His accusations, aired on CBS programme '60 Minutes', come a year after Floyd Landis, another former Armstrong team-mate, made similar allegations of drug use by Armstrong and the team.
