LONDON, FEB 7: Former World 200 metres champion Merlene Ottey has alleged she was asked by athletics World governing body (IAAF) to withdraw from last year's World championships to avoid a drugs scandal. Ottey, who was cleared of any wrongdoing by her National federation in November, was quoted as saying that her agent Daniel Zimmermann received phone calls from two senior IAAF officials asking her to say she was withdrawing from the World championships because of injury.
