Demand for the U.S. automaker’s vehicles slid amid stronger competition from Europe and China and rising anger at Elon Musk’s political forays.

Tesla's China-made electric vehicle sales fell 6% in April from a year earlier, extending declines for a seventh month, as the U.S. automaker grapples with intense competition from its Chinese rivals and a tarnished image in Europe.

New Tesla cars sold in the U.K., Germany, and Spain fell by double digits in April, while China-based BYD has seen an eye-popping 644% surge in Spain this year.
