David Gillick has urged the world governing body for track and field athletics to begin a serious investigation into athletes alleged to have doped, following an expose carried out by The Sunday Times. 

The retired track and field athlete, who won gold in the European Indoor Championships first in Madrid in 2005 and then in Birmingham in 2007, said he would like to see the IAAF seek answers surrounding allegations of doping.

"My whole career, I've put in years of training. 11 months of the year, six days per week, I want to know that if I finished sixth in the world, was it genuinely sixth?" he said, "It'd be great to have that clarity to know if I won a global medal".

He also pointed out that the real effect was not only on the athlete who "lost that moment where you can do a lap of honour with that national flag or stand on the podium and hear your anthem", but there were wider implications for "promoting the sport and giving the belief to the next generation that you can do it, and you can do it clean". 

Speaking on Newstalk Lunchtime with Shona Murray, David explained how athletes dope, and the very dangerous effects it can have on the body.
