UK Athletics chairman Ed Warner insists London's bid to host the 2017 World Athletics Championships will not be derailed by the "background noise" over the future of the Olympic Stadium.
Tottenham and Leyton Orient have won the right to challenge the decision to hand over the stadium in Stratford to West Ham after the 2012 Games. The hearing into the legal challenge is in October.
"The only disappointment is that it still rumbles on as background noise in our bid," Warner said. "We are supremely confident. We've spoken to a lot of the IAAF council members in the last few months [and] they all understand the past is the past."
