Prince Harry fights back tears in court, says UK tabloids made Meghan Markle's life 'an absolute misery'

Prince Harry fought back tears in court as he spoke about his wife, Meghan Markle.

On Wednesday, the Duke of Sussex spent 2½ hours on the witness stand for his lawsuit against Associated Newspapers, publishers of the Daily Mail and Mail on Sunday.

The 41-year-old appeared visibly emotional, telling London's High Court the Daily Mail made Meghan's life "an absolute misery." When he left, Harry looked shaken and was still sniffling.

"Prince Harry closed out his day in court visibly upset," royal commentator Meredith Constant told Fox News Digital.

Associated Newspapers denied the allegations, calling them "preposterous." The publisher said the roughly 50 articles in question were based on legitimate sources, including acquaintances willing to talk about their famous friends.

"No one disputes that Prince Harry and his family endured extraordinary media intrusion," Kinsey Schofield, host of YouTube's "Kinsey Schofield Unfiltered," told Fox News Digital.

"Whether he ultimately wins this case or not, I hope it brings him closure and allows him to focus on the future and the family he's built in California. 

"He's sacrificing precious time with his children to pursue this, and that shouldn't be overlooked. Hopefully, this marks the final chapter for Harry - constantly fighting the world is both emotionally and financially draining."

Harry said private information attributed to "sources" and "friends" fueled his suspicion that people close to him were leaking details to journalists. 

He cited a 2005 article about his girlfriend at the time, Chelsy Davy, that included "an extraordinary level of detail," making him feel he was "part of an endless pursuit - a campaign, an obsession with having every aspect of my life under surveillance."

Harry admitted the coverage made him "paranoid beyond belief" and claimed the outlet wanted to "drive me to drugs and drinking to sell more papers." 

"There was no alternative; I was conditioned to accept it," he said.

Harry said "vicious, persistent attacks" on his wife pushed him to break with royal tradition and take the press to court.

The trial is expected to last nine weeks, with a written verdict likely months away.
