Prince Harry adopted a confrontational stance during his testimony in a lawsuit against the publisher of the Daily Mail. He refuted claims that he had a close relationship with royal family journalists or that his friends leaked information about him to the media.

On Wednesday (Thursday AEDT), Harry insisted, “My social circles were not leaky,” as he engaged in the third and final phase of his legal battle against British tabloids.

During cross-examination, his brief responses and descriptions of life under what he termed “24-hour surveillance” prompted the judge to step in. The judge advised him not to engage in arguments with the defense attorney.

Justice Matthew Nicklin reassured the vexed prince, saying, “You don’t have to bear the burden of arguing the case today.”

Harry, along with seven other high-profile individuals including Elton John and actress Elizabeth Hurley, accused Associated Newspapers Ltd of violating their privacy. Attorney David Sherborne argued that the publication had been involved in a “clear, systematic and sustained use of unlawful information gathering” over a span of two decades.

Associated Newspapers Ltd has denied the allegations, called them preposterous and said the roughly 50 articles in question were reported with legitimate sources that included close associates willing to inform on their famous friends.

Harry says he was ‘paranoid beyond belief’

Harry said in his 23-page witness statement that he was distressed and disturbed by the intrusion into his early life by the Mail and its sister publication the Mail on Sunday, and it made him “paranoid beyond belief”.

Under the English civil court system, witnesses present written testimony, and after asserting that it’s the truth are immediately put under cross-examination.

Harry, dressed in a dark suit, held a small Bible in his right hand in London’s High Court and swore to “almighty God that the evidence I shall give will be the truth, the whole truth and nothing but the truth”. After the Duke of Sussex said he preferred to be called Prince Harry, he acknowledged that his 23-page statement was authentic and accurate.

Defence lawyer Antony White, in a calm and gentle tone, began to put questions to Harry to determine if the sourcing of the articles, in fact, had come from royal correspondents working their sources at official events or from friends or associates of the prince.

As a soft-spoken Harry became increasingly defensive, White said: “I am intent on you not having a bad experience with me, but it is my job to ask you these questions.”

Harry suggested that information had come from eavesdropping on his phone calls or having private investigators snoop on him. He said journalist Katie Nicholl had the luxury to use the term “unidentified source” deceptively to hide unlawful measures of investigation.

“If you complain, they double down on you in my experience,” he said in explaining why he had not objected to the articles at the time.

For decades, Harry has had what he called an “uneasy” relationship with the media, but kept mum and followed the family protocol of “never complain, never explain,” he said.

Articles about Meghan pushed him to sue

The litigation is part of Harry’s self-proclaimed mission to reform the media that he blames for the death of his mother, Princess Diana, who was killed in a car crash in 1997 while being pursued by paparazzi in Paris.

He also said persistent press attacks on his wife, Meghan, Duchess of Sussex, led them to leave royal life and move to the United States in 2020.

He said “vicious persistent attacks,” harassment and even racist articles about Meghan, who is biracial, had inspired him to break from family tradition to finally sue the press.

It is Harry’s second time testifying after he bucked House of Windsor tradition and became the first senior royal to testify in a court in more than a century when he took the stand in his similar lawsuit against the publisher of the Daily Mirror in 2023.

The trial is expected to last nine weeks and a written verdict could come months later.
