Coe declares war on doping New IAAF boss vows to track down cheats

Sebastian Coe vowed "zero tolerance" for drug cheats in track and field after winning Wednesday's narrow vote to become the new president of the IAAF, world athletics' governing body.

Coe edged Ukraine's Sergey Bubka 115-92 in the vote at the IAAF congress in Beijing, but he has a tough task ahead of him.

With a series of doping controversies at the top of Coe's agenda when he takes office after the Aug 22-30 world championships in the Chinese capital, the Briton said he and his new team would be "vigilant" in their crusade against cheats.
