British 800m runner Jenny Meadows has admitted that the latest doping allegations against athletics are "very demoralising".
The IAAF revealed last week that 32 "adverse findings" were picked up in samples of 28 athletes competing at the 2005 and 2007 World Championships.
In 2011, Meadows was only awarded a European Indoor gold medal after the Championships when Russia's Yevgeniya Zinurova was banned for a doping offence.
"You can suspect a couple of people in your event and it's turned out that I have been right," BBC Sport quotes Meadows as saying. "You just don't think that it would happen on a mass scale like that. It has been very, very demoralising."
Meanwhile, Lord Sebastian Coe has been elected as the new president of the IAAF.
