Ros Atkins on... the BBC resignations

The chairman of the BBC has apologised for what he called an "error of judgement" in how a speech by Donald Trump was edited for an episode of Panorama.

The BBC's director general, Tim Davie, and CEO of news, Deborah Turness, resigned on Sunday after a leaked memo criticised the documentary.

But this crisis didn't come out of nowhere, as the BBC's Analysis Editor Ros Atkins explains.
