Lance Armstrong said on Monday that he will participate with “100 per cent transparency and honesty” in any future inquiry into doping in cycling.

The 42-year-old Texan was stripped of the seven Tour de Frances titles he won from 1999 to 2005 and banned from competitive sport for life last year after admitting to using performance-enhancing drugs.

Armstrong, who first revealed that he had cheated in an interview with chat show host Oprah Winfrey in January, said he is willing to help clean up the sport but only if everyone involved is treated fairly.
