Former 200m world champion and Olympic sprint silver medallist Frankie Fredericks says Sebastian Coe is "the best leader," and he will "clean up athletics."

Coe, a former Olympic champion himself, will succeed Lamine Diack as the president of the IAAF, the body that governs world athletics, after beating rival Sergey Bubka, a former Olympic pole vault champion, by 115 votes to 92.

Fredericks told the Â鶹Éç's Ade Adedoyin how big of a challenge the new president is facing.
