"The desire to win medals superseded their collective moral and ethical compass and Olympic values of fair play."

Russian athletes corrupted the London 2012 Olympic Games "on an unprecedented scale", a seven-month investigation into the country's state-run doping programme has revealed.

The findings of the investigation, led by Canadian law professor Richard McLaren and conducted for the World Anti-Doping Agency, were published on Friday.
