If you read Spare, Prince Harry’s tell-all memoir that was published in January, you already know that the younger son of the king of England has a, shall we say, contentious relationship with the tabloid press.

Harry has told the court he's determined to stop the "madness" of news outlets using alleged unlawful activities to obtain personal information.

Prince Harry entered the courtroom on a mission to prove the publisher of the Daily Mirror tabloid hacked his phone and unlawfully snooped.

Prince Harry made a shocking confession during his witness statement in early June. The Duke of Sussex traveled from California to England for his lawsuit against the Associated Newspapers and the Mirror Group.

Harry’s testimony was part of the lawsuit that he and three other plaintiffs have brought against three Mirror titles. The newspaper group has denied wrongdoing.
