Lord Coe: IAAF president on challenge to shape athletics

BBC sports editor Dan Roan speaks to newly elected IAAF president Lord Coe about the challenges he faces to shape the future of athletics.

The 58-year-old Briton - an Olympic 1500m gold medallist in 1980 and 1984 and former London 2012 chairman - succeeds Senegalese Lamine Diack, 82, who has been in charge for 16 years.

Coe beat Ukrainian Sergey Bubka, a former Olympic pole vault champion, by 115 votes to 92.
