Britain's competition regulator launched an investigation into Apple and Google's mobile ecosystems to assess whether they're in breach of strict new tech laws.

Apple Inc. and Alphabet Inc. were hit with UK antitrust investigations over concerns their dominance in mobile services is distorting the market and putting up barriers to entry for competitors.

Britain's Competition and Markets Authority announced investigations into Apple and Google on Thursday to examine if their mobile ecosystems are breaking the country's competition rules.

The country's antitrust regulator said it would investigate whether Apple and Google have strategic market status in their mobile ecosystems, including operating systems, app stores and mobile browsers.

The country’s Competition and Markets Authority is investigating mobile ecosystems controlled by Apple and Alphabet’s Google to work out if they need to obey a strict new law governing digital competition.
