Google is the U.K.’s first big antitrust target after the country quit the European Union as regulators opened a probe Friday into the company’s planned changes to advertising data.
The Competition and Markets Authority said it’s “investigating Google’s plans to remove third-party cookies and other functionalities from its Chrome browser,” according to an emailed statement. This could “undermine the ability of publishers to generate and undermine competition in digital advertising, entrenching Google’s market power.”
