The company reported a 13 percent plunge in sales on Wednesday in another sign that Musk’s embrace of President Trump and far-right politicians in Europe has had a deep and enduring hit to Tesla’s brand appeal.

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.

Tesla is headed for another year of shrinking sales after it posted a second straight drop in quarterly deliveries, dragged down by CEO Elon Musk's right-wing political stances and an aging vehicle line-up that has turned off some buyers.
