Intro:

Former Tour de France winner Greg LeMond said he wants a fundamental shake-up at the top of cycling as he joined pressure group Change Cycling Now in calling for International Cycling Union (UCI) president Pat McQuaid to step aside in London on Monday.

Script:

SOUNDBITE: (English) Paul Kimmage, former cyclist and journalist: "Stuff (doubt over Wiggins being clean) that should never have happened, were Dave Brailsford (performance director of British Cycling and general manager of Team Sky) true to his word, when the team was established.

Were he true to his word, the mess Bradley Wiggins is in now - because believe me, it is a mess, and the mess is the uncertainty out there about the credibility of it (Wiggins' Tour de France win) - that would never have happened, should never have happened, had David Brailsford delivered on what he set out to do. Transparency."

SOUNDBITE: (English) Dr Michael Ashenden, blood doping expert: "We need to change the environment that the riders are put into. We can't do that without knowing what has led to this situation, what was keeping it in place - the riders are the ones that can tell us that. If we put a zero tolerance in place, they're not going to be able to help. It's simply asking too much of someone to sacrifice themselves. And anyway, that would be futile. The greater good is to change the environment and because of that priority, I don't see a place for zero tolerance at the moment. After a truth and reconciliation process, then is the time for zero tolerance - but not today."
