Prince Harry is bringing the action along with others including actresses Elizabeth Hurley and Sadie Frost, Sir Elton John, and his husband, filmmaker David Furnish.
Prince Harry has arrived at the High Court as legal proceedings in an Associated Newspapers phone-tapping and privacy case begin.
He is one of several claimants in the lawsuit filed against the publisher of The Daily Mail newspaper.
Associated Newspapers denies the allegations, and a preliminary High Court hearing begins today to consider legal arguments before a judge decides whether the case will proceed.
A smiling prince was seen arriving at the Royal Courts of Justice in central London, flanked by bodyguards, dressed in a suit and tie and a black winter coat, and surrounded by reporters and photographers.
Harry, 38, is joining actresses Elizabeth Hurley and Sadie Frost, Sir Elton John and his husband, filmmaker David Furnish, and Baroness Doreen Lawrence of Clarendon OBE in bringing the action.
They claim they were victims of “abhorrent criminal activity” and “gross breaches of privacy” by Associated Newspapers Limited and announced in October that they were filing claims for misuse of private information against ANL, which also publishes The Mail On Sunday and MailOnline.
The alleged illegal acts included hiring private investigators to secretly place listening devices inside cars and homes, secretly recording private phone conversations, illegally accessing bank accounts, and paying police officials for inside information.
The accusations have been called “preposterous smears” and a “pre-planned and orchestrated attempt to drag the Mail titles into the phone-hacking scandal,” according to the publisher.
According to an ANL spokesperson, the allegations are “unsubstantiated and highly defamatory claims based on no credible evidence.”
The four-day hearing will include ANL’s request that the claims be dismissed without a trial.
