Donald Trump has lashed out at the BBC over its Panorama edit of his January 6 speech by accusing the broadcaster of being “corrupt, fraudulent and criminal”.In a new allegation levied at Broadcasting House, the US President suggested the BBC might have used artificial intelligence when doctoring his speech.Speaking from the White House, the US President said: “The BBC, it was incredible what they did. They had me speaking something I had never said. I’ve never seen anything like it.”He added: “They put words in my mouth, and they actually said I said some pretty bad things. I didn’t say it. It was AI-generated.”Mr Trump filed a $10billion lawsuit against the BBC after its Panorama programme spliced together two clips in a 12-second segment from the 2021 Capitol riots in its 2024 Trump: A Second Chance? documentary.In the clip, Mr Trump supposedly said: “We’re going to walk down to the Capitol and I’ll be there with you, and we fight. We fight like hell.”However, it later emerged that the footage had been “mangled” together with a 50-minute gap separating the two moments.During an appearance alongside Irish Taoiseach Micheál Martin to mark St Patrick’s Day, the US President alleged that the BBC goes beyond “fake news”, a phrase the former property tycoon helped popularise during his 2016 White House campaign.US President Donald Trump lashed out at the BBC and Sir Keir Starmer during his appearance at the White House | GETTYMr Trump, who admitted he watched the BBC for some “crazy reason” this morning, said: “I am very proud of the term ‘fake news’ because it was my term, I came up with it, but it’s really no longer accurate.”It’s corrupt, fraudulent, it really is. It’s beyond fake, it’s criminal what they do.”However, Mr Trump’s outburst comes just hours after the BBC called on judges in Florida to throw out the US President’s lawsuit.The BBC argued there was a “chilling effect” in Mr Trump pursuing legal action, particularly given the Panorama programme never aired in the US. New Broadcasting House in central London | PAThe broadcaster also categorically rejected Mr Trump’s suggestion that it had admitted to defaming him.In court documents filed yesterday, BBC lawyer Charles Tobin wrote: “Given the many allegations prior to the documentary’s release regarding plaintiff’s January 6 speech — and that shortly after its release, the President won re-election and carried Florida by a wide margin — plaintiff cannot plausibly claim that the documentary harmed his reputation.”During Mr Trump’s sit-down with Mr Martin, the US President also renewed his war of words with Sir Keir Starmer.The Prime Minister initially refused to allow US bombers to use RAF bases to launch strikes on the Islamic Republic, sparking fury from the White House. Pro-Trump protesters had stormed the Capitol Building on January 6, 2021 | GETTYSpeaking this afternoon, Mr Trump said: “We have a tremendous long-term relationship with the UK. People would say it’s the best. It was the longest. The oldest should be the best.”Always was the best until Keir came along. I like him. He’s a nice man. He says everything beautifully. He’s a very nice man with a beautiful family.”The US President also reiterated his opposition to Sir Keir’s stances on both immigration and North Sea oil.Meanwhile, Broadcasting House is under increasing pressure to reveal how much licence fee funding is being spent on the $10billion lawsuit.Sir Keir Starmer’s relationship with Donald Trump has worsened over recent weeks | GETTYEx-BBC executive producer Martin Rosenbaum told GB News the clandestine approach could only hold for so long and that it was right to share the cost of the case with the public.“I’d expect the BBC to reveal the details of the legal costs of the case after it is completed, whenever that is,” he said.“It’s right that this information should then be disclosed in the public interest. I wouldn’t expect them to release such figures while the case is ongoing, for the reasons reported.”Charlie Moloney, a veteran journalist and co-editor of McNae’s Essential Law for Journalists, concurred in his own analysis of the BBC’s rejection of the FOI request.Donald Trump made the claims in an appearance alongside During an appearance alongside Irish Taoiseach Micheál Martin | GETTY“One day, when the dust settles, the BBC will have to reveal how much this case cost, and that may not be a happy day for whoever has by then become director-general,” he told The People’s Channel.“Legal costs are a key consideration in any litigation. But in this case, the amount of money being spent by the BBC is perhaps more important than the theoretical legal merits of President Trump’s claim and the BBC’s potential defence.“President Trump seemed to believe the BBC, fearful of being seen to waste licence payer money on legal costs, would blink first and settle this case. The BBC has instead resolved to defend its journalism.“The corporation could come under political pressure at home to settle if the cost of this litigation was made clear through FOIs. That would prejudice the BBC’s ability to run its chosen defence.”GB News has approached the BBC for comment.
