The IAAF has moved to deny claims that president Sebastian Coe knew of bribes being offered or received ahead of the vote for the 2017 World Championships.
In an interview with BBC Radio 5 live's Sportsweek programme this month, UK Athletics chairman Ed Warner revealed he received a warning from a "very senior person in the IAAF hierarchy", who said he understood Qatari officials were handing out brown envelopes prior to the vote.
A report on Thursday alleged Coe, who appeared on the same Sportsweek programme, was the person referred to by Warner.
However, an IAAF spokesperson said: "Sebastian Coe had no actual knowledge of bribes being offered or received linked to the 2017 World Championship.
"As he and Ed Warner discussed on 5 live Sportsweek there was rumour piled upon rumour in the days leading up to the bid as is often the case on these occasions."
Doha's bid was beaten by London, with Qatar's capital was subsequently awarded the 2019 championships.
Coe, a vice-president of the IAAF when the 2017 vote took place in November 2011, has expressed his determination to clean up athletics in the wake of recent doping scandals.
Warner, meanwhile, told a British parliamentary committee hearing this week that Doha's bids for the 2017 and 2019 championships have been referred to the IAAF's ethics commission.
