BBC director general Tim Davie and his head of news, Deborah Turness, have resigned.
The BBC had come under fire over a Panorama documentary that was accused of misleadingly editing a speech by Donald Trump to make it look like he was urging people to attack the US Capitol.
In emails to staff, both Davie and Turness said mistakes had been made.
Tim Davie was appointed director general of the BBC in September 2020. He was in charge of overseeing the corporation's services and was its editorial, operational and creative leader.
He was not a new figure to the BBC; prior to becoming director general, he had been chief executive of BBC Studios for seven years.
