France’s financial prosecutor has recommended the former president of world athletics ruling body the IAAF, stand trial for alleged corruption and money-laundering, sources with direct knowledge of the matter told Reuters on Monday.

The French probe began in November 2015 with Lamine Diack being put under formal investigation on suspicion of receiving bribes to cover up doping violations by Russian athletes. He has denied the allegations.

The financial prosecutor also said that Diack’s son Papa Massata Diack was also under investigation over corruption allegations. He too denies wrongdoing.

The investigative judge has three months to decide on the financial prosecutor’s recommendation that Diack and his son stand trial.
