Russia's State-Sponsored Doping Programme (2015)

The McLaren Report revealed that Russia operated a state-sponsored doping programme involving over 1,000 athletes across 30 sports from 2011 to 2015. At the 2014 Sochi Winter Olympics, FSB agents swapped dirty urine samples through a hole in the wall of the anti-doping laboratory. Russia was banned from competing under its own flag at the 2018 and 2022 Olympics — the most sweeping sanction in Olympic history — though critics argue the punishment was still too lenient.
