“The challenge for him over the years to come is to bring the public and having authorities closer together, and to prospect the evolution and strengthening associated with compliance with the new code. “

UK Sport chief executive Liz Nicholl added: “I am delighted to see the new Wada code has harder sanctions for doping but also offers scope to encourage athletes to reveal information which may lead to the authorities being able to root out more medications cheats from elite sport. “
