More than a 1,000 athletes were doped in a conspiracy involving Russia’s secret service, claims report

More than 1,000 athletes were being doped by Russian officials over a four-year period from 2011, a new report claims.

The McLaren report, the final part of which was released today, says there was a massive cover-up at the heart of the Russian sport programme which "corrupted the London games on an unprecedented scale". Five medallists from the London 2012 games and four from the winter games in Sochi in 2014 are implicated in the report, but the author, Professor Richard McLaren who was appointed by the World Anti-Doping Agency, said the corruption was widespread - and could even have included the use of the Russian secret services. "There was a cover up that evolved into an institutional and disciplined medal-wining strategy," he said. He wrote how the programme of doping was implemented at the London games and then refined for the 2013 World Athletics Championships in Moscow and the Sochi Winter Olympics in order to give Russian athletes the best chance of winning medals - and then protecting them when they did.

"The desire to win medals superseded their collective moral and ethical compass and Olympic values of fair play." Russia won 21 golds at the London games, and 72 medals in total. At Sochi they took 33 medals, including 13 golds. Russian officials have denied the claims while the International Olympic Committee has called for more evidence. IOC president Thomas Bach said the report's findings would be looked into by two commissions before any further action is taken. "As soon as we have the report it will be handed over to the two commissions, who have already undertaken preparatory work," he Bach. "But if you ask me for my private opinion then personally if you have an athlete being part of such a manipulation system, clearly I would not like to see this person compete again."
