The program implicated Ajan in “financial irregularities, corruption, doping control distribution, doping sample manipulation, doping payment irregularities, doping activities in specific nations and nepotism,” the IWF said.
The 81-year-old Ajan has stood aside from his 20-year presidency of the IWF during the probe. He was general secretary for the previous 24 years.
Ajan, an International Olympic Committee member and then honorary member for the past 20 years, denies wrongdoing. He has said the investigation will vindicate him.
McLaren has a proven record of delivering investigative reports on a tight deadline. His work verifying a Russian whistleblower’s claims of state cheating and cover-ups at the 2014 Sochi Olympics led to intense legal processes for clearing some athletes to represent Russia at the 2016 Rio de Janeiro Games.
McLaren’s team includes lead financial investigator Steve Berryman, the IWF said. As an Internal Revenue Service agent, Berryman was a lead investigator in a sprawling investigation of financial corruption in international soccer linked to senior FIFA officials.
Acting IWF president Ursula Papandrea said the organization needed independent people outside the sport — “someone who is not a friend of weightlifting” — to investigate the allegations.
