London ? The head of the British Broadcasting Corp.’s main television channel resigned Friday over the editing of footage that was seen to wrongly imply that Queen Elizabeth II walked out abruptly from a portrait sitting with photographer Annie Leibovitz.

BBC1 controller Peter Fincham resigned after an independent inquiry released Friday criticized “misjudgments, poor practice and ineffective systems” at the BBC. Stephen Lambert, head of RDF Media Group, which made the program, also resigned Friday.

The BBC apologized to the queen in July after it aired for journalists a trailer for the forthcoming documentary. The queen, in fact, was entering the room, not leaving it. But in the editing of the footage, it appeared she walked out suddenly after Leibovitz asked her to remove her crown for a photo. The trailer was never shown on TV.
