US President Donald Trump has vowed to buy a “brand new Tesla” in a show of support for his adviser, tech billionaire Elon Musk, after one of the worst one-day share price falls in the carmaker’s history.
Tesla – owned by Mr Musk – has seen its shares plunge since the start of the year, plummeting by more than another 15% on Monday to its lowest level since the end of October as sales of the electric car firm comes under pressure from Chinese rivals.
