IAAF president Lord Coe says the corruption scandal facing athletics is not “bigger” than that facing Fifa in football, with both governing bodies under criminal investigation.
Lamine Diack, Coe’s predecessor, is being investigated by French officials, and the bidding process to host the 2021 World Championships is also under scrutiny.
Fifa has also faced widespread corruption allegations this year.
Fifa president Sepp Blatter is the subject of a Swiss criminal investigation, started alongside a US inquiry which has indicted several top executives. Blatter denies any wrongdoing.
Asked if athletics’ scandal was bigger than Fifa’s, Coe said: “I don’t actually believe that.”
He told BBC Radio 4’s Today programme: “I’m not walking away from the seriousness I’m confronting but we are talking about a criminal investigation that is looking at a handful of people.
“That’s of no comfort to me because I’m still having to do the things I’m doing now on an hourly basis to make changes.”
