British athletes will forfeit right to compete if caught doping

Great Britain's athletes heading to this month's World Indoor Championships in Portland will sign declarations forfeiting their right to compete for their country again if found guilty of a serious doping offence -- and British Athletics performance director Neil Black wants to see other countries introduce a similar agreement.

Black does not expect any of his 23-strong squad, which is headlined by Olympic and world long jump champion Greg Rutherford, to refuse to sign the anti-doping contract.

"The ideas have actually come from athletes and so we are thinking that athletes are going to be generally supportive of the whole concept," he said.

The plans for the agreement were revealed in January as British athletics chiefs looked to take a lead in tackling the doping crisis which has brought the sport to its knees.

"The clause has now been completed and it will go out with the normal correspondence in the next 24 hours or so," Black said. "It's a common-sense piece of administration."

Asked what the response would be should an athlete refuse to sign, he said: "Not envisaging that."

He added: "We want there to be good processes and good practices throughout the world. We want other people to follow through with things in ways that are very similar or the same as we do."

The championships in Portland, which run from March 17-20, will take place without Russia, who are banned from international competition over state-sponsored doping.
