Beijing: Britain’s Sebastian Coe was elected as new International Association of Athletics Federation (IAAF) president at the 50th IAAF Congress here on Wednesday.

Coe, a former Conservative Party lawmaker and a member of the House of Lords, a two-time Olympic 1,500-meter champion and chief organiser of the 2012 London Olympics, beat Ukrainian pole vault great Sergei Bubka and won the vote 115-92 in the IAAF election held on the eve of the world championships in Beijing, as per reported.

Former president Lamine Diack, who has been at the helm for 16 years, left with the track and field’s international governing body under criticism after media allegations that he failed to act on evidence of widespread blood doping.

While both candidates called for an overhaul of the way the anti-doping programme is run, Coe was more forceful against critics by describing the accusations as a “declaration of war”.

Britain’s The Sunday Times newspaper reported earlier in August that one-third of medals in endurance races at the Olympics and world championships were won by athletes who have recorded suspicious blood readings.
