Usain Bolt insists he is a 'clean' athlete
Sprint champion insists that fans can rest assured he is not a drugs cheat

Six-time Olympic champion Usain Bolt insists he is a "clean" athlete and that fans can trust him despite recent failed drugs test by sprint rivals Asafa Powell and Tyson Gay.
"I was made to inspire people," Bolt told a London news conference yesterday, ahead of his return to the London Olympic track today where he will run in the 100 metres at the Diamond League Anniversary Games.
"I was given a gift, I know I'm clean. For me it happens [failed dope tests], I'm not going to stress about it," added Bolt, the 100m and 200m world record holder.
Bolt's Jamaican compatriot Powell, the former 100m world record holder, tested positive for the banned stimulant oxilofrine at national trials last month and is still waiting to discover whether analysis of his "B" sample confirms the original finding.
United States sprinter Gay also tested positive for the same stimulant in an out-of-competition test in May.
However, Bolt, 26, refused to condemn either of his rivals.
