Murray blasts Puerto order
Andy Murray has waded into the row over Operacion Puerto by blasting a Spanish court's order that the evidence be destroyed as "a joke".
The British tennis No 1 called the order to destroy more than 200 blood bags "the biggest cover-up in sports history".
It comes after Eufemiano Fuentes, a doctor specialising in sports medicine, received a suspended one-year jail term for providing blood-doping services to cyclists.
Some 211 blood bags from 35 different people - believed to include a number of athletes from different sports - were seized as part of Operacion Puerto when Spanish police raided Fuentes' laboratory in 2006.
However, the Madrid judge has rejected requests from anti-doping authorities and international sports federations to be allowed to analyse the blood bags and has ordered that they be destroyed.
That decision has been blasted by Murray, who said on Twitter: "operacion puerto case is beyond a joke... biggest cover up in sports history? why would court order blood bags to be destroyed? #coverup".
UK Anti-Doping chief executive Andy Parkinson has also criticised the Spanish court's order.
He said: "We are disappointed in the decision by the Spanish authorities. Dr Fuentes has admitted to having been involved in multiple prohibited doping activities, and linked with multiple unnamed athletes.
"It therefore cannot be right that these names will remain unknown and that no immediate action can be taken by the anti-doping community to protect our clean athletes."
WADA also expressed its disappointment at the decision to dispose of the evidence and is currently weighing up whether to appeal.
A statement on its website said: "The decision to order the destruction of all the blood bags is particularly disappointing and unsatisfactory for WADA, and the whole anti-doping community.
"WADA is currently fully reviewing the decision and any possible appeal or other action with its Spanish legal advisors, and the Spanish National Anti-Doping Organisation (AEA). The deadline to appeal the case is 17 May."
