Apple, Google Face New Antitrust Investigations in U.K.

The U.K.’s competition regulator wants to investigate market power it says Apple and Alphabet Google exert over some mobile-device software, ramping up global antitrust scrutiny of the largest U.S. technology companies.

The Competition and Markets Authority said Friday that it intends to initiate so-called market investigations into how the companies control web browsers for mobile devices, as well as complaints that Apple restricts cloud gaming on its devices. Under U.K. rules, market investigations can lead to binding orders to change practices, but no fines.
