The president of Athletics South Africa has resigned from the board of the sport's governing body in protest at the IAAF's treatment of 800 metre winner Caster Semenya.
Leonard Chew-in-yay says Semenya's not accused of trying to cheat but of perhaps unknowingly having a medical condition that blurs her gender, and says they aren't going to allow Europeans to describe and define South Africa's children.
Semenya was greeted by around a thousand flag-waving fans on her arrival at Johannesburg airport.
