Dwain Chambers can finally breath a sigh of relief as the 100m sprinter has been given the approval to compete at the London 2012 Olympic Games. In 2003 he was banned from competing at the Olympics for testing positive for using performance enhancing drugs.

The Court of Arbitration for Sport looked into whether the British Olympic Association’s (BOA) life ban on all athletes convicted of serious doping offences was illegal and found that the BOA’s law didn’t comply with the World Anti-Doping Agency’s global code meaning that Chambers, along with other athletes who have previously tested positive to using performance enhancing drugs, can compete in this summer’s Games.

This June Chambers will have the chance to qualify for the Games at the UK Trials and Championships at Alexander Stadium in Birmingham.  We’re guessing that anti-drug-cheat campaigner Paula Radcliffe won’t be a happy bunny.
