Lamine Diack, the former president of the International Association of Athletics Federations (IAAF), was responsible for organizing and enabling the conspiracy and corruption that took place in athletics' governing body, an independent commission of the World Anti-Doping Agency (WADA) said Thursday.

The commission was delivering the second part of its report, whose first installment in November led to the banning of Russia from athletics for state-sponsored doping.

Diack, who was replaced by Sebastian Coe as president in August, is under investigation by French police for corruption and was heavily criticized by the report.
