And reaction from across the sports spectrum has been coming in following the report. The IOC could take the first sanctions against Russia, and the Olympic committee says the report will be 'carefully' studied and 'provisional measures and sanctions' could be decided when its members hold an emergency conference call later today.

IOC president Thomas Bach called it "a shocking and unprecedented attack", he also added that "The IOC will not hesitate to take the toughest sanctions available against any individual or organisation implicated."

The President of the International Paralympic Committee, Philip Craven says "We are truly shocked, appalled and deeply saddened at the extent of the state sponsored doping programme implemented in Russia ahead of Sochi 2014." He added that "The findings of the McLaren report mark a very dark day for sport."

WADA also said Russian government officials should also be denied access to international competitions, including Rio 2016. The organization's president Craig Reedie said Russia must fire government officials implicated in the doping scheme. He said that "At a minimum, Russian Anti-Doping Agency return to compliance cannot be considered until all persons from the Russian Ministry of Sport and other government departments implicated, including RUSADA, are dismissed from their roles."

IAAF President Sebastian Coe says "The institutionalized and systematic doping in Russian athletics is the reason the IAAF suspended, and then upheld the suspension of, RusAF's membership and consequently the exclusion of their athletes from international competition."
