One of the worlds biggest tech firms is now heading to the court room.

Apple has been charged with breaking EU competition rules over the way it runs its App Store.

The latest charge relates to the previous one brought two years ago by music streaming app Spotify which claimed that Apple was stifling innovation in that industry.

Apple faces a large fine and may be forced to change its policies if its arguments do not convince regulators.

Apple has denied any wrongdoing.

The European Commission opened up two antitrust investigations into Apple’s App Store and Apple Pay practices last year, and the Financial Times only mentions upcoming charges on the App Store case. It’s not clear yet what action will be taken.
