Jan. 19 (UPI) -- Prince Harry was in London's high court on Monday for the start of a case against a British tabloid publisher.

Harry, Elton John and Elizabeth Hurley are among seven plaintiffs alleging Associated Newspapers Limited has used unlawful methods to gather information on them, breaching privacy.

Associated Newspapers Limited publishes the Daily Mail and The Mail. It denies the allegations.

The trial is being held at the Royal Courts of Justice.

Among the allegations, plaintiffs say the publisher deployed private investigators, tapped and hacked their telephones and obtained private medical and financial records.
