Not the perfect script, says Coe

Justin Gatlin's win in the 100 metres at the World Athletics Championships was "not the perfect script", IAAF president Sebastian Coe said on Sunday.

"I'm not eulogistic that someone who has served two bans has walked off with one of our glittering prizes. But he is eligible to be here," Coe, the head of the sport's governing body, said.

"It's not the perfect script. I thought Usain was very generous with the observations he made. That must have been a bitter event for him to swallow. He was bigger than the moment and it typifies his career."

Coe reiterated his support for life bans for drug cheats after Jamaica's prime minister Andrew Holness said he wanted the measure introduced to fully eradicate cheating.
