Lord Coe's position as the president of athletics' world governing body could be at risk over "very, very disturbing" allegations about his knowledge of Russia's doping problems, a senior MP has suggested.
Conservative Jesse Norman, who chairs the Culture, Media and Sport select committee, said the "jury is out" on whether he has confidence in Lord Coe in his current role as IAAF president.
Mr Norman added he expects the Tory peer to return before the committee to answer further questions, with an apology to Parliament among the potential measures available if it is shown he misled MPs.
An investigation by the BBC's Panorama programme has claimed Lord Coe may have misled Parliament in 2015 about what he knew, and when, about the doping scandal.
The IAAF has said Lord Coe was right to pass on to the ethics commission information he received in 2014 about allegations of a plot to blackmail a Russian athlete over blood results.
It said the ethics commission told Lord Coe it was already aware of the allegations which were being ''actively investigated'', so he left the case with them.
