The High Council of Sport said it had sent a report on the anti-doping agency to Spanish prosecutors following an investigation into a complaint. It alleged "irregularities in the use of public funds and the control and sanctioning of doping". Spanish media outlet Relevo reported this week that the country's anti-doping agency had exploited bureaucratic loopholes to cover up positive cases.

The council, led by Jose Manuel Rodriguez Uribes, called for the resignation of CELAD director Jose Luis Terreros because of the "damage to the reputation" of Spanish sport and the anti-doping agency.

If Terreros does not resign, Uribes and the Minister of Education and Sport, Pilar Alegria, will try to have him removed, the council said. 

Uribes reaffirmed "Spain's commitment to ensuring that all athletes compete on equal terms and that the purity of sport prevails" and said they would "cooperate faithfully" with the World Anti-Doping Agency (WADA). WADA criticised Spain's anti-doping agency on Friday, threatening potential "significant consequences for Spanish sport" if doping cases are not handled properly. 

"We are well aware of the deep-seated problems within the Spanish anti-doping system," said WADA President Witold Banka. "I am disappointed with the level of cooperation we have received from CELAD as we seek to improve the system for Spanish athletes."  WADA said the matter was still under "full investigation".
