Baku, June 6, AZERTAC

Prince Harry entered a courtroom witness box Tuesday, swearing to tell the truth in testimony against a tabloid publisher he accuses of phone hacking and other unlawful snooping, AP reported.

Harry held a Bible in one hand as he was sworn in at the High Court in London, where he is suing the publisher of the Daily Mirror. Earlier, he’d arrived at court in a black SUV and entered a modern wing past dozens of photographers and TV cameras.

Harry accuses the publisher of the Mirror of using unlawful techniques on an “industrial scale” to get scoops. He faces hours of cross-examination by a lawyer for the defendant, Mirror Group Newspapers, which is contesting the claims.

Sitting in the witness box and dressed in a dark suit and tie, Harry told Mirror Group attorney Andrew Green that he had “experienced hostility from the press since I was born.” The prince accused the tabloids of playing “a destructive role in my growing-up.”

Harry was forced almost immediately to acknowledged that he couldn’t recall specific articles he was complaining about. Green pressed him on how they could have caused such distress if he couldn’t remember having read them at the time.

“It isn’t a specific article, it is all of the articles,” he said. “Every single article has caused me distress.”

Green asked him to identify what evidence he had of phone hacking in specific articles, and Harry said he’d have to ask that question of the journalist who wrote it. He repeatedly said that the manner in which information had been obtained was highly or incredibly suspicious.

He said that it was also suspicious that some of the journalists had been known for hacking or invoices to third parties, including private investigators known for snooping, around the time of the articles.

When asked how reporters could have hacked his phone for an article about his 12th birthday — a time when he admitted he didn’t have a mobile phone — he suggested they may have hacked the phone of his mother, the late Princess Diana.

“That’s just speculation you’ve come up with now,” Green suggested.

In the same article, Green pointed out that a reference to him taking his parent’s divorce badly was obvious.

“Like most children I think, yes,” Harry said.

But the prince said it was not legitimate to report such information and “the methods in which it was obtained seem incredibly suspicious.”

Green then pointed out that his mother previously made public comments to reporters about the difficulties of her children after the divorce.

The 38-year-old son of King Charles III is the first senior British royal since the 19th century to face questioning in a court. An ancestor, the future King Edward VII, appeared as a witness in a trial over a gambling scandal in 1891.

Harry has made a mission of holding the U.K. media to account for what he sees as their hounding of him and his family.

Setting out the prince’s case in court Monday, his lawyer, David Sherborne, said that from Harry’s childhood, British newspapers used hacking and subterfuge to mine snippets of information that could be turned into front-page scoops.

He said that stories about Harry were big sellers for the newspapers, and around 2,500 articles had covered all facets of his life during the time period of the case — 1996 to 2011 — from injuries at school to experimenting with marijuana and cocaine to ups and downs with girlfriends.
