Kiwi David Howman will lead Athletics' battle against dopers and cheaters.

The former director general of the World Anti-Doping Agency has been appointed as the head of the IAAF's newly established Integrity Unit.

Having been a top official at WADA for 13 years, IAAF President Lord Sebastian Coe says Howman is the perfect choice.

David Howman's role will address issues of doping, bribery, corruption, betting and the manipulation of competition results in athletics.
