Sochi samples of Russians to be reanalysed

The International Olympic Committee (IOC) announced Friday that it will reanalyse all 254 urine samples taken from Russian athletes who took part in the 2014 Sochi Winter Olympics.

The IOC said it had also extended the mandate of its own Oswald disciplinary commission to examine all samples collected from Russian athletes during the London Summer Olympics in 2012.

The decisions were taken, the IOC said, following the publication Friday of Richard McLaren's full report into doping in Russia that revealed an "institutional conspiracy" by Moscow to cheat between 2011-15.

All 63 blood samples collected from Russian athletes in Sochi have already been reanalysed by the IOC in cooperation with McLaren. All came back negative.

The IOC said the urine samples would be retested because "McLaren's mandate did not include a full reanalysis of all these samples".
