Is cheating in sport endemic, will the London Olympics be ‘clean’, what are the lasting effects on sport, why would an athlete risk going from national hero to a figure of contempt and, most importantly in the case of drugs, what are the lasting effects on the human body?

The whole issue of cheating in sport will be discussed by Richard Moore, award-winning sports journalist with several books to his name including the soon-to-be-published The Dirtiest Race in History: Ben Johnson, Carl Lewis and the Olympic 100m Final; Dave Farrar, a commentator and writer on a variety of sports, who has personal knowledge of gambling and is author of The Perfect Punter: A Year of Losing Everything and Trying to Win it All Back; and Chris Cooper, a top biochemist at the University of Essex, who looks at drugs in sport in Run, Swim, Throw, Cheat: The Science Behind Drugs in Sport. The debate is chaired by cycling journalist Daniel Friebe.
