He says no evidence of doping will be discovered and expressed his surprise that the investigation is still ongoing.

"Nowhere would a case have been started on those grounds, but in Paris they did.

"They knew the evidence was clean but kept the case open and so it continued to be a joke.

"The case is not finished yet, they can keep it open but there is nothing there."

Suspicious

Armstrong also said he was concerned about a growing cynicism in regards to drugs controversies in sport.

"I don't know if our sport will ever be vindicated. I think it's much bigger than me," he said.

"It's a question of cycling, of endurance sports and of Olympics sports and of professional sports. It's an epidemic.

"They're going to question when somebody breaks the 5000m record on the track, they're going to question things when somebody does something in the swimming pool.

"A lot of cynics will say that is just not possible.

"The champions, the best and the record breakers will never be vindicated.

"Unfortunately it's very damaging to people, to teams, to sponsors and reputations, but it never stops and I don't think it ever will."
