Tim Davie has resigned as the BBC's director general following criticism that a Panorama documentary misled viewers by editing a speech by US President Donald Trump.

Deborah Turness, the corporation's head of News, has also stepped down from her role over the issue.

Davie, who has been in the job for five years, had faced increasing pressure over a series of controversies.

The Telegraph published details of a leaked internal BBC memo on Monday that suggested the Panorama programme edited two parts of Trump's speech together so he appeared to explicitly encourage the Capitol Hill riots of January 2021.

Announcing his resignation on Sunday evening, Davie said: "Like all public organisations, the BBC is not perfect, and we must always be open, transparent and accountable.

"While not being the only reason, the current debate around BBC News has understandably contributed to my decision.

"Overall the BBC is delivering well, but there have been some mistakes made and as director general I have to take ultimate responsibility."

In Trump's speech in Washington DC on 6 January 2021, he said: "We're going to walk down to the Capitol, and we're going to cheer on our brave senators and congressmen and women."

However, in the Panorama edit he was shown saying: "We're going to walk down to the Capitol... and I'll be there with you. And we fight. We fight like hell."

The two sections of the speech that were edited together were more than 50 minutes apart.
