Prince Harry's "mission" against the British press has resulted in a victory against Rupert Murdoch's the Sun, which has admitted to wrongdoing.

A legal battle brought by Prince Harry against the publisher of The Sun newspaper, owned by media mogul Rupert Murdoch, kicked off at the High Court in London on Tuesday, without Prince Harry in attendance and with several delays.

Prince Harry claimed victory in his long-running legal battle against Rupert Murdoch's British newspaper group, after reaching a deal to settle his lawsuit which included an apology for unlawful actions relating to the Sun for the first time.
