Prince Harry has drawn Prince William and Princess Kate into his ongoing legal fight against the Daily Mail’s publisher, escalating tensions within the Royal Family.
According to new details submitted to the High Court, the Duke of Sussex claims that private investigators spied on the Prince of Wales and accessed personal data linked to Kate during their younger years.
Invoices Point to Surveillance of Royals
Lawyers for Harry presented invoices allegedly showing surveillance activity around Prince William’s 21st birthday party, as well as searches connected to Catherine Middleton, Kate’s maiden name.
One 2003 invoice refers to a £350 payment for “Out of Africa Story Royal Party Enqs” tied to William’s 21st birthday celebrations. Another mentions mobile phone data belonging to Catherine Middleton, while additional records show searches linked to the Middleton family home. A separate document listed 10 numbers from a “family and friends” contact sheet, with Kate’s highlighted among them.

These documents, Harry’s team argued, were discovered within five boxes of invoices described as “highly significant” and only handed over last week. His barrister, David Sherborne, told the court that the files had not been fully reviewed but already appeared “highly relevant” to the wider case.
