David Millar of Garmin-Sharp secured a brilliant breakaway success on Stage 12 of the Tour de France before reiterating his belief that cycling has cleaned up its act on doping.

Millar revealed to Ned Boulting he had been determined to win the stage all along, and put faith in himself to win the final sprint.

He also said the victory holds particular significance on the 45th anniversary of British cycling legend Tom Simpson's death.

"Because we've lost our GC hopes, I have been allowed to do what I want and I'm taking advantage of it," Millar said. "I was determined today - I said to myself: 'I'm going to win today' and I was going to do whatever it took."

Asked about the significance of winning on the anniversary of Tom Simpson's death, Millar added: "It is particularly poignant given what I've been through, an ex-doper who's now clean and loves his sport.

"I am very proud today to do it today because we mustn't forget Tommy's memory and because of what this sport's been through and where we are now.

"We are the cleanest we've ever been and, with Brad [Wiggins] leading and Chris [Froome] second, we are clean riders and we are dominating the Tour de France.

Millar became the fourth British rider to win a stage at this year's Tour de France - all four riders are on the Men's Olympic Road Race.
