LONDON -- SoftBank Group's decision to sell its U.K. chip designer Arm Holdings has cast a shadow over the U.K. economy's already-bleak prospects after the country left the European Union. There are growing concerns that the purchase of Arm by U.S. chipmaker Nvidia may see jobs depart.
The BBC calls Arm the "crown jewel" of the U.K. technology sector, as the company's chip designs are used in more than 90% of the world's smartphones.
