Ukrainian athlete Lyudmila Blonska has been stripped of her silver medal in the Olympic heptathlon after she tested positive for steroids.
The athlete was handed over a ban of two years in 2003 for testing positive to steroids and now faces a lifetime ban.
Kelly Sotherton, who finished fifth in the event in which Blonska got the silver medal, called for a worldwide policy for preventing drug cheats from returning to compete in the Olympics.
