Adidas, the IAAF's biggest sponsor, has told 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.
Adidas, which designs and manufactures sports shoes, clothing and accessories, has also expressed its displeasure at the corruption scandal that continues to engulf Fifa.
However, the German firm, which signed a £750m kit sponsorship deal with British football giants Manchester United in 2014, remains the oldest commercial partner of world football's governing body.[/B]
