Stadium row puts 2017 bid at risk

London's bid to host the 2017 World Championships could be derailed by the legal dispute over the Olympic Stadium.

Tottenham Hotspur have sought a judicial review of the decision to hand the stadium to West Ham. IAAF president Lamine Diack said members would be deterred by a lengthy dispute. "If the legal problems are continuing you must convince my colleagues and many of them will say no," he said.
