Adidas to pull out of IAAF deal

Adidas, the IAAF's biggest sponsor, has told the athletics' world governing body it is to terminate their sponsorship deal four years early.

The sportswear giant informed the IAAF of its decision — understood to be a direct result of the doping scandal sweeping the sport - last week.

Sources say the move will cost the IAAF and its commercial partner Dentsu tens of millions of dollars in revenue.

Neither Adidas nor the IAAF — the International Association of Athletics Federations - confirmed the split but both issued short statements. —BBC
