IAAF chief Sebastian Coe has denied that he misled a British Parliamentary committee investigating doping in sport when he appeared before it last December.

Central to Coe's evidence was his insistence that he did not know the specific detail of an email sent to him by former London Marathon race director David Bedford, which Coe says he sent to the IAAF Ethics Commission without opening the attachments.

Bedford told the Parliamentary Committee this month that he was surprised to hear that Coe had not read the attachments of the 2014 mail and committee chairman Damian Collins said Bedford's evidence had raised questions over "the timing and extent of Lord Coe's knowledge of these allegations."
