A hearing on remaining issues and legal costs will take place next month.
The MGN case is just one of four Harry is pursuing at the High Court. He has won the right to take to trial a similar phone-hacking case against Associated Newspapers, the publisher of the Daily Mail and Mail on Sunday, which he has brought with high-profile figures including singer Elton John.
Allegations of unlawful behaviour by News Corp’s News Group Newspapers, the publisher of the Sun, will also go to trial.
“I’ve been told that slaying dragons will get you burned,” Harry’s statement said. “But in light of today’s victory and the importance of doing what is needed for a free and honest press – it’s a worthwhile price to pay. The mission continues.”
