Top British cyclist David Millar has gone on trial in Paris charged with breaking French anti-doping laws.
The Scot and seven other members of his former French team Cofidis are facing charges of "acquiring and holding banned substances".
Miller, 29, was banned for two years after confessing to the use of blood booster erythropoietin in 2004 but returned to action in June this year.
An inquiry into Cofidis followed and will form the basis of the case.
Three other three defendants - a cycling technician, a pharmacist and a former Cofidis physio - also face charges.
These stem from their alleged role in supplying the riders with performance-enhancing drugs.
The defendants each face up to five years in prison if found guilty.
Other riders to stand trial are Frenchmen Robert Sassone, Mederic Clain and Philippe Gaumont, Daniel Majewski of Poland and Italian Massimiliano Lelli.
Millar returned to competition in this year's Tour de France after serving his ban and is now riding for the Saunier team.
