Chambers is defiant

The disgraced British sprinter Dwain Chambers has said he definitely won't give up his dream of once again competing in the Olympics - and that means targeting London in 2012.

Dwain Chambers spoke to ITV News in an exclusive interview about his fight over drugs in sport and his hopes for the future.

He lost his legal fight to overturn a lifetime Olympic ban for using drugs.

But he said that he has served his time and, like everyone he deserved a second chance.

And despite the Olympic ban, he's determined to continue in other international athletics competitions.

He also believes that despite more stringent testing, Beijing won't be a drug free games.
