Chambers, 29, who has returned to competition after serving a two-year doping suspension, is considering a legal challenge to the BOA's lifetime Olympic ban for any athlete failing a drugs test.

"There will be no room for cheats in the British team as long as I am involved with the BOA," Moynihan told the BBC.

"There are absolutely no grounds whatsoever for compromise."

Chambers won a silver medal in the 60 metres at the world indoor championships this month but his future is uncertain after leading European promoters said he would not be welcome at their meetings.
