Prince Harry, the Duke of Sussex, has reportedly faced a major setback in his latest legal battle — one that recently drew in Prince William and Kate Middleton.

Last week, it was revealed that Harry had included his brother and sister-in-law in new allegations connected to his ongoing lawsuit against the publisher of the Daily Mail, Associated Newspapers Limited (ANL). However, those fresh claims have now been dismissed by a High Court judge.

Harry is one of seven high-profile figures accusing ANL of “grave breaches of privacy.” The other claimants include Baroness Doreen Lawrence, Sir Elton John and his husband David Furnish, actress Elizabeth Hurley, former MP Sir Simon Hughes, and actress Sadie Frost.

The claimants allege that the publisher engaged in unlawful practices such as phone hacking, home bugging, and obtaining private medical and financial information through dishonest means. ANL has repeatedly denied the accusations, insisting the claims were made “far too late.”

During a preliminary hearing last week, Harry’s barrister, David Sherborne, reportedly sought to add a new set of allegations — suggesting that Prince William, Kate Middleton, and even the late Princess Diana may also have been targets of unlawful information gathering.
