BBC chairman Samir Shah has apologised for a Panorama documentary which edited a clip of a speech by Donald Trump, calling it an "error of judgement".

"We accept that the way the speech was edited did give the impression of a direct call for violent action," Shah said in a letter to the Culture, Media and Sport Committee.

Both the BBC's director general Tim Davie and head of news Deborah Turness resigned on Sunday following criticism that the programme, aired in October 2024, gave the impression Trump explicitly encouraged the Capital Hill riot in January 2021 by placing two different parts of the speech together.
