Campbell: Chambers not solely to blame

Olympic gold medalist Darren Campbell continues to maintain disgraced sprinter Dwain Chambers cannot be held “solely accountable” for his drug abuse.

Former European 100 metres champion Chambers, 30, has now returned to competitive action after his two-year suspension for testing positive for designer steroid tetrahydrogestrinone (THG) in 2003, and won a silver medal at the World Indoor Championships in Valencia earlier this year.
