UK competition watchdog warns big tech firms of investigations

Companies such as Google, Facebook, Amazon and Apple face increased scrutiny from CMA

The UK's competition watchdog plans to launch a series of antitrust investigations into big tech companies including Google and Amazon this year, in the latest sign of increased scrutiny of the practices of the Silicon Valley companies.

The Competition and Markets Authority will later this year become home to a new digital markets unit (DMU), which will police the internet companies and have powers to impose fines worth billions of pounds.
