Davie tells staff departure was ‘my own decision’ but it comes with the BBC preparing to apologise for the way it edited a Trump speech

Tim Davie, the BBC’s director general, and the head of BBC News have resigned after a former adviser to the corporation accused it of “serious and systemic” bias in its coverage of issues including Donald Trump, Gaza and trans rights.

In a shock move, Davie said his depature was his own, but comes with the BBC preparing to apologise for the way the broadcaster edited a Donald Trump speech.

Deborah Turness, head of BBC News, has also resigned. It follows claims by a former adviser to the broadcaster that it suffered from bias.

The Commons culture, media and sport select committee has given the BBC a deadline of Monday to respond to the claims made by Michael Prescott, a former independent external adviser to its editorial guidelines and standards committee (EGSC). He left that role in the summer.
