The Duke of Sussex has settled the remainder of his phone hacking claims against the Mirror Group.

The Duke of Sussex, 39, sued Mirror Group Newspapers (MGN) for damages, claiming journalists at its publications were linked to methods including phone hacking, so-called “blagging” – gaining information by deception – and use of private investigators for unlawful activities.

In December, a judge ruled that phone hacking became “widespread and habitual” at MGN titles in the late 1990s and was practised “even to some extent” during the Leveson Inquiry into press standards in 2011.

Mr Justice Fancourt concluded that Harry’s phone was hacked “to a modest extent” by MGN, awarding him £140,600 in damages.

Thirty-three articles in Harry’s claim were examined during the trial last year, with 15 articles found to have been the product of unlawful information gathering.

A further 115 articles were in his claim, which may have been the subject of a further trial.

During today’s hearing in London, Harry’s barrister David Sherborne confirmed a settlement had been reached between the duke and MGN, stating they will pay him a “substantial additional sum by way of damages and all the costs of his claim.”

Harry’s case at trial was heard alongside similar claims brought by actor Michael Turner, who is known professionally as Michael Le Vell and is most famous for playing Kevin Webster in Coronation Street, actress Nikki Sanderson, and Fiona Wightman, the ex-wife of comedian Paul Whitehouse.
