Lord Coe 'honoured' after being elected IAAF president

Former Olympic 1500m champion Lord Coe says he is "honoured" and "flattered" at being elected president of athletics' world governing body, the IAAF.

The 58-year-old Briton, who was London 2012 chairman, succeeds Senegalese Lamine Diack, 82, who has been in charge for 16 years.

Coe also addresses the doping issues by insisting there is a zero tolerance to the abuse of doping.
