A BBC documentary entitled "Panorama: Buying the Games", which aired in August 2004, investigated the taking of bribes in the bidding process for the 2012 Summer Olympics. The documentary claimed that it was possible to bribe IOC members into voting for a particular candidate city. After being narrowly defeated in their bid for the 2012 Games, Parisian mayor Bertrand Delanoë specifically accused the British prime minister Tony Blair and the London bid committee, headed by former Olympic champion Sebastian Coe, of breaking the bid rules. He cited French president Jacques Chirac as a witness; Chirac gave guarded interviews concerning his involvement but the allegation was never fully explored. Turin's 2006 Winter Olympic bid was also clouded by controversy. A prominent IOC member, Marc Hodler, closely connected to the rival bid of Sion, alleged bribery of IOC officials by members of the Turin Organising Committee. These accusations led to a wide-ranging investigation, and also served to sour many IOC members against Sion's bid which potentially helped Turin to capture the host city nomination.
