Food and drink giant Nestle has ended its sponsorship of the IAAF, as it fears the doping scandal engulfing the world athletics governing body could damage its reputation.
The Swiss company said it had taken the decision with “immediate effect”.
However, the IAAF said it was still “in discussion” with Nestle over the final year of its sponsorship deal.
Last month, sportswear giant Adidas ended its sponsorship deal with the IAAF.
“We have decided to end our partnership with the IAAF Kids Athletics programme with immediate effect,” Nestle said.
“We believe this could negatively impact our reputation and image and will therefore terminate our existing agreement with the IAAF, established in 2012.
“We have informed the IAAF of our decision and await a formal acknowledgment from them that our partnership has ended.”
For its part, the IAAF emphasised the number of children that would be affected by Nestle’s decision.
“In 2016, IAAF Kids’ Athletics plans to reach a further 15 countries, training 360 lecturers, instructing 8,640 physical education teachers, with three million children participating by the end of the activation,” the athletics governing body said.
The IAAF is reeling in the face of widespread allegations of corruption and bribery. New president Lord Coe was brought in to clean up the organisation, and has been travelling the world trying to ease the concerns of corporate sponsors.
The loss of Nestle, coming so soon after Adidas, is a big blow to the body.
While Nestle was in the final year of its deal, Adidas’ 11-year sponsorship deal, reportedly worth $33m (£23m), was due to run until 2019.
However, sources have told the BBC the figure was much higher and worth up to $8m a year.
