IAAF president Sebastian Coe faces a huge challenge to restore public trust in the organisation after his predecessor, Lamine Diack, was accused of "organising and enabling conspiracy and corruption" within athletics' governing body on another dark day for the sport.
The second part of a report by an independent commission established by the World Anti-Doping Agency (WADA) was published on Thursday, with one of the conclusions being that the highest levels of the IAAF Council must have known about the extent of doping.
Athletics' reputation was severely tarnished last November when the first part of the report made allegations of state-sponsored doping in Russia, which led to the IAAF suspending Russian athletes from competition.
