The McLaren Report has found that Russia operated a state-run doping programme for four years across the vast majority of summer and winter Olympic sports.
The programme was planned and operated from late 2011 until August 2015, in the build-up to the London 2012 Summer Games and the Sochi 2014 Winter Olympics.
The report, an independent investigation commissioned by the World Anti-Doping Agency, revealed that the Russian sports ministry "directed, controlled and oversaw" the manipulation of urine samples collected from its athletes.
The two-month long investigation was led by Dr Richard McLaren and confirms much of what Grigory Rodchenkov has stated.
Rodchenkov claimed he was the head of the laboratory that made cocktails of drugs to be distributed to Russian athletes, amongst other illegal activities.
“The findings of the report show a shocking and unprecedented attack on the integrity of sport and on the Olympic Games,” said IOC President Thomas Bach.
As a result of this latest report, there is likely no chance of the IAAF ban on Russian athletes participating in the Olympics being overturned.
The World Anti-Doping Agency (WADA) has already come out with its own recommendation that Russian athletes be banned from Rio.
In addition, WADA says Russian government officials should also be denied access to international competitions, including Rio 2016.
A statement on the WADA website said: “Accordingly, WADA recommends to the International Olympic Committee (IOC) and the International Paralympic Committee (IPC) to consider, under their respective Charters, to decline entries, for Rio 2016, of all athletes submitted by the Russian Olympic Committee (ROC) and the Russian Paralympic Committee.
“Furthermore, any exceptional entry of a Russian athlete should be considered by the IOC and IPC for participation under a neutral flag and in accordance with very strict criteria.
“WADA also recommends that Russian Government officials be denied access to international competitions, including Rio 2016.”
