Tyler Hamilton - Former professional cyclist

For years, it's been one of the biggest questions in sport.

Did Lance Armstrong - the seven time winner of cycling's greatest race, the Tour de France - dope?

Is the man who beat cancer to become one of the greatest sporting figures ever - a cheat?

Armstrong has denied wrongdoing.

But now a former teammate and roommate of Armstrong's, Tyler Hamilton, has produced the most detailed and wounding set of allegations yet.

Is Hamilton self-serving and greedy, as Armstrong insists?

Or a shaft of light on a sport that's been mired in murk?
