Moscow - Timeline of Russian doping and corruption scandals after the International Olympic Committee said on Tuesday it will study "legal options" before deciding whether to ban Russia from the Rio Games over its state-run doping programme.
German broadcaster ARD airs documentary alleging systematic doping in Russian athletics. A week later, Russian athletics chief and IAAF treasurer Valentin Balakhnichev, and IAAF marketing consultant Pape Massata Diack, son of then-IAAF president Lamine Diack, step down while corruption and doping allegations are investigated by IAAF's ethics commission. WADA then sets up an independent commission headed by its former chief, Dick Pound, to investigate the claims.
ARD airs second documentary with new accusations aimed at Russian and Kenyan athletes based on a leaked IAAF database with details of 12,000 blood tests from 5,000 competitors which revealed "extraordinary" levels of doping. Sebastian Coe is elected to succeed Diack as IAAF president later that same month.
French police charge Lamine Diack with corruption on suspicion the 83-year-old Senegalese accepted bribes to cover up doping cases. Diack also charged with money laundering and conspiracy.
WADA's report into the scandal calls on Russia's track and field team to be banned from international competition, including from the 2016 Rio Olympics, until "state-sponsored" doping is eradicated.
The IAAF's 26-strong council subsequently suspends the Russian athletics team. WADA also suspends Russia's national anti-doping body, RUSADA, over non-compliance.
IAAF ethics commission bans for life Balakhnichev and Pape Massata Diack over bribes taken to cover up doping failures by Russian athletes.
WADA's second report into doping and corruption is published. It says IAAF leaders must have known about the wide scope of doping.
The former head of Russia's anti-doping laboratory, Grigory Rodchenkov, exiled in the United States, describes an organised doping campaign including at least 15 medallists from the 2014 Sochi Winter Olympics, with the close involvement of the sports ministry and the FSB security service.
Three days after calling the claims "absurd", Russian Sports Minister Vitaly Mutko says he is "ashamed and sorry".
Another ARD programme claims that Russian authorities have been covering up for coaches disgraced by the doping programme, directly pinpointing Mutko for his alleged involvement in the cover-up.
The IAAF Council unanimously votes to extend the ban on the Russian athletics federation, but offers an Olympic lifeline to athletes training outside the Russian system to compete in Rio as neutrals.

The IAAF clears only US-based long jumper Darya Klishina to compete in Rio, after 136 Russian athletes applied for exemption from the blanket ban. Klishina later tells AFP that she has been branded a traitor back home.

Canadian law professor Richard McLaren releases a 96-page report for WADA which outlines rampant Russian state-run doping at the Sochi Olympics and other major sports events.
The investigation finds the FSB secret service helped "the state-dictated failsafe system" carried out by the sports ministry and covering 30 sports.
WADA consequently calls for Russia to be banned from the Rio Olympics in August and urges global sports governing bodies to bar Russia until "culture change" is achieved.
IOC president Thomas Bach describes the revelations as "a shocking and unprecedented attack" on sport.

Russia's Sports Minister Vitaly Mutko is barred from attending the Rio Games and the IOC orders a disciplinary commission to look into his ministry's role detailed in the McLaren report.
The IOC puts back a decision on whether to bar Russia from Rio - barely two weeks away - and will also await a Court of Arbitration for Sports decision on an appeal by 68 Russian athletes against the IAAF blanket ban from competition. That was expected on Thursday.
