Wada acts on Russian doping but has it gone far enough?

Last year an independent World Anti-Doping Agency (WADA) investigation exposed state-sponsored Russian doping.

This was the overwhelming thrust of Monday's independent commission report into allegations of Russian doping.

Below is an explanation of the key players and issues in the Russian doping saga.

Wada says Russian doping was rife during this period.

The recent uncovering of shocking systematic Russian doping has levels of suspicion at an all-time high.

The IOC and CAS have been complicit in enabling Russian doping, Walden said in a statement.

He said the overall handling by the IOC of the Russian doping affair was far from perfect.

The Russian doping scandal puts a spotlight on a problem that was already systemic in international sports.

To this has now been added the Russian doping scandal and the IOC's hapless response to it.

He had reportedly contacted a journalist shortly before his death, offering to speak out about Russian doping.

This may be the end of the 'meatwagon' story, but the Russian doping saga is still playing out.

Rodchenkov was the head of the Russia's anti-doping laboratory and a key player in Russian doping at Sochi.

That was expected to bring an end to the Russian doping affair until the evidence of tampering was unearthed.

Skeleton athletes from the United States are also considering pulling out of the championships in protest at Russian doping.

Athletics is on its knees with the Russian doping crisis which is the latest in a string of embarrassing scandals.
