Seven-time Tour de France winner Lance Armstrong has once again insisted he never took performance-enhancing drugs during his career.
The American's career was tainted by the allegations, with French newspaper L'Equipe claiming he tested positive for EPO during the 1999 Tour, but he has consistently denied ever being "doped."
And speaking in his first major newspaper interview since retiring from cycling two years ago, Armstrong has maintained his stance.
He tells Sport: "Many people must say 'he'll need to confess some day'. I'm sorry, but I won't admit to something I've never done.
"I will never say 'yes, I was doped'. And I will never say it because I never did it.
"Look at my career from the age of 15 until my retirement - where is the indisputable proof? You'll be looking for a long time. It doesn't exist."
L'Equipe devoted four pages to its most recent allegations in 2005, under the front-page headline 'The Armstrong Lie', which claimed that signs of EPO were found in six of the American's urine samples in 1999.
But he says: "L'Equipe wrote that I was positive on the basis of a test carried out on a B sample.
"When I saw that, I thought: 'Well now, how can I defend myself?' There was no way out since the athlete's rights had been trampled on."
