The US has filed a landmark lawsuit against Apple which accuses the tech giant of monopolising the smartphone market and crushing competition.
It accuses the California-based company of stopping competitors from offering rival services on the iPhone while also making it difficult for users to switch to alternative operating systems. "Consumers should not have to pay higher prices because companies break the law," Mr Garland said, accusing Apple of "locking its customers in" while at the same time "locking its competitors out".
A justice department official told CBS, the BBC's US partner, that if prosecutors succeeded at trial they could force Apple to alter contracts, or possibly even make structural changes within the company.A spokesman for Apple, Fred Sainz, told US media that the lawsuit was "wrong on the facts and the law" and that Apple would "vigorously defend against it".
Anat Alon-Beck, a business law professor at Case Western Reserve University in Ohio, told the BBC that Apple "systematically" excludes rivals from its ecosystem.
