Sir Dave Brailsford has hit back at those doubting Team Sky's clean approach to cycling by pointing to the consistent achievements of the Great Britain cycling team.
Team Sky's dominant displays over the last 12 months have led some to speculate on the validity of their success in a sport once marred by doping, but Brailsford angrily refutes those rumours which continue to follow his team.
The Team Sky principal, who masterminded British Cycling's eight gold medal-haul at the Beijing and London Olympics, told cyclingnews.com: "If you're a cheat, you're a cheat, you're not half a cheat.
"You wouldn't say, 'I'll cheat here but I'm not going to cheat over there; I'll cheat on a Monday but not on a Tuesday.'
"So we were doping in the Olympics too? If I'm a doper, if I'm a liar, I'm a liar in my personality through and through.
"So why didn't I dope the Olympic team for the last 15 years? Have I just decided I'm going to do it with this team? I'm not going to do it over there but I'll cheat here? Full gas.
"But we've dominated the Olympic games for 15 years. Explain that to me. We didn't just win at the Olympic Games, we dominated them, we smashed it out of the park. More than anyone else has ever done. That level of performance is monumental.
"If I'm a liar and a cheat and if my ethics and morals are all about cheating, if that's what we're doing here, lying to the world and cheating, then surely I'll be doing it in other places in my life. Not just parts."
Team Sky's control of major stage races - their tactics of riding at the front of the peloton, controlling the pace and countering attacks - have also been criticised in some quarters, but Brailsford also defended those tactics.
"If people want the entertainment value of riders attacking each other, stopping, attacking each other again and again, then go back to 'old cycling', which will give you the capability to do that," he added.
"If you want clean sport and clean cycling, then it's going to be different. You can't have it both ways. There's an element of reality about what we're doing."
