King Charles hosted an AI summit at Dumfries House, warning of existential risks from artificial intelligence, including the danger that it could develop capacities to take life, and urging an urgent discussion on balancing risks and rewards. The summit included tech leaders such as the boss of Nvidia. AI pioneer Yoshua Bengio, interviewed on the programme, said the warnings were serious and compared the need for global action to the pandemic, calling for international regulation and cooperation between the US and China. He acknowledged that President Trump had dismissed AI fears as a hoax but said scientific facts are undeniable, and he expressed hope that the upcoming Xi-Trump meeting could be a historic opportunity for agreement.

Separately, fresh claims emerged from a book by Princess Diana's brother, Earl Spencer, serialized in the Daily Mail, alleging that the then Prince Charles sounded 'giddily elated like a lottery winner' in a phone call after Diana's death in 1997. The book also described a dispute over whether Princes William and Harry should walk behind their mother's coffin. Buckingham Palace responded that grief can cloud memory over time. Former palace press secretary Dickie Arbiter, a guest on the programme, rejected the claims, saying Charles was devastated and calling Spencer's account 'hogwash'. The discussion also touched on whether the palace should respond further, with panellists noting that the public has other concerns and that the story may quickly fade.
