The one-hour programme, Trump: A Second Chance?, was broadcast last year and was made for the BBC by independent production company October Films Ltd, which has also been approached for comment.

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 Panorama’s 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 President Trump discussed how “corrupt” US elections were. In total, he used the words “fight” or “fighting” 20 times in the speech.

After showing the president speaking, the programme played footage of flag-waving men marching on the Capitol, the Telegraph said.

According to the leaked memo, this “created the impression President Trump’s supporters had taken up his ‘call to arms'”. But that footage was in fact shot before the president had started speaking.

On 6 January 2021, hundreds of Trump supporters stormed the US Capitol, protesting about Joe Biden’s election victory. Five people died in relation to the riot.

The House of Representatives accused Trump of encouraging violence with false claims of election fraud, but he was acquitted of an impeachment charge that he incited a mob to storm the Capitol.

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”.

Speaking to GB News on Tuesday, Badenoch said: “That is fake news, actually putting different things together to make something look different from what it actually was.

“And I do think heads should roll. Whoever it was who did that should be sacked, that’s what Tim Davie should be doing, identifying who put out misinformation, and sacking them.”

She continued: “The public need to be able to trust our public broadcaster… They should not be telling us things that are not true.

“This is a corporation that needs to hold itself to the highest standards, and that means that when we see people doing the wrong thing, they should be punished, they should be sacked.”

Former prime minister Boris Johnson also said the corporation needed to respond, asking on X:, external “Is anyone at the BBC going to take responsibility – and resign?”
