John Fahey - President, World Anti-Doping Agency

Anti-doping authorities in Britain will carry out more than 7,000 drugs tests on athletes at the London Olympics and Paralympics later this year, more than at any previous games. They're also warning potential cheats that the 2012 Games will be the 'riskiest yet' with a greater chance of them getting caught.But, despite the rhetoric, the British Olympic Association also faces the overturning of its lifetime Olympic ban for any athlete banned for more than six months for a doping offence. The World Anti-Doping Agency says the BOA's stance is not compliant with its code. What message does this send in an Olympic year, and what can WADA do to combat what it sees as the growing role of organised crime in the trafficking of performance enhancing drugs? Tim Franks speaks to WADA's President, John Fahey.
