Why has Tim Davie resigned and what was the Trump documentary edit?

Last week, the Daily Telegraph published an exclusive report, saying it had seen a leaked internal BBC memo. The memo came from Michael Prescott, a former independent external adviser to the broadcaster's editorial standards committee. He left the role in June. The memo suggested that the one-hour Panorama documentary had edited parts of Trump's speech together so he appeared to explicitly encourage the Capitol Hill riots of January 2021. In his speech in Washington DC on 6 January 2021, Trump 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. The "fight like hell" comment was taken from a section where Trump discussed how "corrupt" US elections were. In total, he used the words "fight" or "fighting" 20 times in the speech. According to the Telegraph, the document said Panorama's "distortion of the day's events" would leave viewers asking: "Why should the BBC be trusted, and where will this all end?" When the issue was raised with managers, the memo continued, they "refused to accept there had been a breach of standards". The BBC has come under scrutiny over a number of other different issues in recent weeks. The Telegraph also reported that Mr Prescott raised concerns about a lack of action to address "systemic problems" of anti-Israel bias in the coverage of the Gaza war by the BBC Arabic news service. The report also said Mr Prescott had raised concerns about the BBC's coverage around trans issues. And on Thursday, the BBC upheld 20 impartiality complaints over the way presenter Martine Croxall earlier this year altered a script she was reading live on the BBC News Channel, which referred to "pregnant people".
