The former head of UK anti-doping, Michele Verroken, has told talkRADIO she is "mystified" over the International Olympic Committee's (IOC) decision not to ban Russia's athletes from the Rio 2016 Olympic Games.
While its track and field athletes have already been blocked from entering the Olympic athletics competition – by the sport's governing body the International Association of Athletics Federations – Russia escaped a blanket ban across the entire Games in a ruling handed down by the IOC yesterday (Sunday).
The IOC said they would allow governing bodies of individual sports to decide if Russian athletes are clean and should be allowed to take part in the Games, which begin on August 5.
The Institute of National Anti-Doping Organisations called the decision "a sad day for clean sport.
Verroken, formerly director of ethics and anti-doping at UK Sport, told Paul Ross: "There you have an organisation [the IOC] meant to be in leadership of Olympic values.
"Most of us are completely mystified as to how they've treated doping in sport.
"What we've promised them [whistleblowers] through the world anti-doping code, we don't plan to fulfill.
"I think this is hugely disappointing."
