Questions will be asked of individual athletes, national bodies, and those who worked on the IWF’s former “independent” Anti-Doping Commission as to why there was no attempt to pursue normal procedures after samples had been provided.

The role of anti-doping agencies may also be an issue.

Details of IWF doping cover-ups were revealed in June by McLaren, who also pointed out that 24 out-of-competition tests taken before the 2015 IWF World Championships in Houston in Texas were “highly suspicious”.

Weightlifting has been plagued by doping scandals for decades and its place on the Olympic Games programme has been called into question in the 1980s and more recently.

It lost 64 athlete quota places from its Rio 2016 total and is due to have 196 athletes competing at the postponed Tokyo 2020 Olympics next year.

Soon after McLaren said Aján had overseen “systemic governance failures and corruption at the highest level”, the IWF’s interim president Ursula Papandrea said, “My main goal is to create an organization worthy of our athletes, member federations, and maintaining Olympic status.

“The investigation findings are shocking and disconcerting, to say the least.

“The current Constitution and by-laws are such that little to no oversight is required and the political culture that has become the norm is absolutely unacceptable.

“The lack of checks on operations has allowed misdeeds that have robbed the sport of robust and responsive development.

“The [McLaren] findings afford the IWF the opportunity to rebuild and reform the organization.

“This is not an option but an absolute necessity.”
