The director general of Britain’s BBC, Tim Davie, and the CEO of news, Deborah Turness, have resigned following criticism over bias at the corporation, including in the way it edited a speech by US President Donald Trump.

The document suggested the flagship Panorama programme had edited two parts of Trump’s speech together so he appeared to encourage the Capitol riots.

“This is entirely my decision, and I remain very thankful to the Chair and Board for their unswerving and unanimous support throughout my entire tenure, including during recent days,” Davie said in a statement.

“I have been reflecting on the very intense personal and professional demands of managing this role over many years in these febrile times, combined with the fact that I want to give a successor time to help shape the Charter plans they will be delivering.”

Trump in the BBC documentary was shown telling his supporters that “we’re going to walk down to the Capitol” and that they would “fight like hell”, a comment he made in a different part of his speech.
