Anti-doping expert hits back at Coe

One of the experts at the centre of allegations the IAAF turned a blind eye to potential mass doping in athletics has written an open letter to Sebastian Coe accusing the world governing body of lacking the drive to clean up the sport.
Michael Ashenden was one of the two anti-doping experts enlisted by the Sunday Times who analysed leaked data belonging to the IAAF, which contained more than 12,000 blood tests from 5,000 athletes, and concluded hundreds of athletes had recorded suspicious results which were not followed up.`
