Prince Harry has accused tabloid newspapers of hacking his voicemails when he was a teenager, saying it made him feel he "couldn't trust anybody".
Appearing in court in his case against Mirror Group Newspapers (MGN) he said he has "experienced hostility from the press" since he was born.
He is the first senior royal to give evidence in court in over 130 years. MGN's lawyer said he had sympathy for the duke, but denied journalists' actions were "all unlawful".
Prince Harry arrived on Tuesday morning at London's High Court dressed in a dark suit and looking relaxed - dozens of journalists only had a matter of seconds to get their photographs as he made his way swiftly into the building.
