Eufemiano Fuentes, the doctor at the centre of a Spanish doping probe, could be jailed for up to two years for crimes against public health, a Madrid court said.

The court said in a statement prosecutors have asked for a two-year sentence for Eufemiano Fuentes and six others, including his sister Yolanda and former cycling team directors Manolo Saiz, Vicente Belda and Jose Ignacio Labarta.

The World Anti-Doping Agency (WADA) has expressed its frustration at the refusal by judicial authorities of Spain to allow them access to evidence from the operation.
