Sprinter Dwain Chambers is one of the most controversial selections in Team GB's athletics squad, having served a two-year doping suspension and having to overturn a ban from the Games in the courts.
But having won the right to compete in London, Chambers must now find form after a disappointing final run at Crystal Palace before the Games, where he failed to get out of his heat.
School Reporters from The John Fisher School in Purley spoke to Chambers at Crystal Palace, asking him about his display and his feelings ahead of the Olympics.
