Justin Gatlin’s 100m victory at the World Championships in London was “not the perfect script”, says Lord Coe.

American Gatlin, 35, who has twice served a doping ban, pulled off a shock win to end Usain Bolt’s reign in the Jamaican’s final individual race.

“I’m not eulogistic that someone who has served two bans has walked off with one of our glittering prizes,” said Coe, who is president of athletics’ governing body the IAAF.
