Elon Musk appears to have many obsessions. The world's richest man is evangelical about electric vehicles, space travel and Donald Trump. Another of his interests may yet have profound consequences for the UK: British politics. The billionaire is reported to be thinking of becoming the biggest donor in history with a rumoured 80m payment to Nigel's Farage's Reform UK party. Like so many who embraced Trump's bellicose brand of rightwing populism, Musk was radicalised by his frustration at lockdowns, according to Musk watchers.

Former Prime Minister David Cameron has been hired by a US artificial intelligence company. Mr Cameron, who quit UK politics in the wake of the 2016 EU Referendum, will lead Afiniti's advisory board. The firm said his "experience of political leadership through periods of complexity" would be invaluable. Mr Cameron has kept a relatively low profile since leaving UK politics - his autobiography is due to be published in September. He is also president of Alzheimer's Research UK and chairs the board of patrons at National Citizen Service.
