# Shares in electric car maker Tesla have slumped more than nine-percent after EU and UK sales fell by almost half in January. The drop took the company’s valuation back below one-trillion-dollar for the first time since November 2024. Tesla sales last year fell for the first time in more than a decade as demand faltered and rivals gained pace. In addition, Tesla owner Elon Musk has been causing controversy on both sides of the Atlantic as a close ally of US president Donald Trump.
