Elon Musk's electric car firm Tesla pushed the government to make petrol car drivers "pay more" in the days after Labour won the general election.
Musk, the chief executive of Tesla, has waded into British politics openly on social media, predicting "civil war" and criticising prime minister Sir Keir Starmer.
But behind the scenes his firm was trying to persuade the new government to extend a policy that would boost his firm's profits.
The company called for the mandate to boost electric car sales to be extended to lorries, and said electric vehicle (EV) subsidies could come from charging people buying petrol and diesel cars.
