IAAF stops changes of allegiance, will set up new system

The governing body of world athletics (IAAF) has put an immediate stop to changes of nationality by athletes, saying the system has become open to abuse and rules are being manipulated. IAAF President Sebastian Coe said a working group would be set up to agree new rules by the end of the year. "It has become abundantly clear that with regular multiple transfers of allegiance, especially from Africa, the present rules are no longer fit for purpose," Coe told reporters on Monday.
