The fallout from athletics’ corruption and doping scandals continued on Wednesday as Nestlé terminated its sponsorship of the IAAF’s global Kids Athletics scheme a year early because it felt the link was damaging its public image.

It is another blow to the sport’s global governing body. Last month Adidas reportedly pulled out of a contract worth about £5.6m a year which was due to end in 2020, although its logo is still on the IAAF’s website.

Sebastian Coe, the IAAF president, said that his organisation wouldn’t allow Nestlé to end the deal, which funds 15 million children aged seven to 12 years old in 76 countries. “I am angered and dismayed by today’s kids’ athletics announcement,” said Coe in a statement. “We will not accept it. It’s the kids who will suffer.”

In a statement Nestlé, a sponsor of the IAAF since 2012, said: “We have decided to end our partnership with the IAAF Kids programme with immediate effect. This is our decision given the negative public perception regarding corruption allegations and doping in sport against the IAAF. We believe that this could adversely affect our reputation and image and therefore have terminated the existing contract.

The IAAF insisted it was still in discussions with Nestlé and stressed the benefits of the relationship. “This has been a successful programme which promotes a healthy, active lifestyle,” it said in a statement. “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.”

Meanwhile the two Kenyan athletes who are serving four-year bans for doping at the 2015 world championships have accused the chief executive of Athletics Kenya of asking each of them for a $24,000 bribe to reduce their suspensions.

The 400m runner Joy Sakari and the hurdler Francisca Koki Manunga told Associated Press that the Athletics Kenya chief Isaac Mwangi asked for the payment in a meeting in October, but that they could not raise the money. They were then were told of their four-year bans in emails a month later, but never filed a criminal complaint because, they say, they had no proof to back up their bribery accusation and also feared repercussions. Mwangi dismissed the allegation as “just a joke”, adding: “We have heard stories, athletes coming and saying: ‘Oh, you know, I was asked for money. But can you really substantiate that?” Sakari and Manunga have said they will testify to the IAAF’s ethics commission .

UK Anti-Doping has signed a deal to deliver a testing programme in Russia. The World Anti-Doping Agency confirmed the deal would continue until the Russian Anti-Doping Agency is compliant with the Wada code.

In a statement, Wada said: “Ukad will ensure that targeted and intelligence-led testing is carried out on Russian athletes, and is responsible for continued coordination with the appropriate sport federations during this period. Results management of all cases will be managed by a designated independent body, with full oversight by Wada.”
