Sales at Elon Musk’s Tesla have fallen to a three-year low amid the billionaire’s public spat with Donald Trump. The electric carmaker said customer deliveries fell by 13.5pc in the second quarter of the year, a period in which Mr Musk left his role in the White House and publicly fell out with the US president over his tax and spending bill.

Trump, making his first comments on Musk’s criticism of his bill during an Oval Office press conference, insinuated the Tesla CEO opposes his “One Big Beautiful Bill Act” because he is “upset” the electric vehicle tax credit was removed, adding he’s not sure he’ll remain friends with Musk and alleging Musk “knew the inner workings of the bill.”
