Sebastian Coe has received crucial backing to remain as IAAF president despite another damning report on athletics’ doping scandal and admitting that he leads a “failed organisation”.

The International Association of Athletics Federations has sought to take the sting out of upcoming doping claims by revealing and denying allegations due to be published this weekend.

Twenty-eight athletes have been suspended over historic doping offences, the International Association of Athletics Federations announced last night.

The International Association of Athletics Federations says it will not rule out “any follow-up action necessary” over a Sunday Times report alleging widespread doping in the sport.
