The news comes shortly after Prince Harry issued a strong defense of his wife Meghan Markle amid what he described as the “ruthless” treatment she has received in the British tabloid press.

“Unfortunately, my wife has become one of the latest victims of a British tabloid press that wages campaigns against individuals with no thought to the consequences — a ruthless campaign that has escalated over the past year, throughout her pregnancy and while raising our newborn son,” Harry said.

The royal went on to say that he and Meghan have “continued to put on a brave face – as so many of you can relate to – I cannot begin to describe how painful it has been.”

His statement came as the royal couple launched legal action against the Mail on Sunday in the U.K.

A legal spokesperson from Schillings, who is representing the Duchess of Sussex, said: “We have initiated legal proceedings against the Mail on Sunday, and its parent company Associated Newspapers, over the intrusive and unlawful publication of a private letter written by the Duchess of Sussex, which is part of a campaign by this media group to publish false and deliberately derogatory stories about her, as well as her husband. Given the refusal of Associated Newspapers to resolve this issue satisfactorily, we have issued proceedings to redress this breach of privacy, infringement of copyright and the aforementioned media agenda.”

Harry added that he has been “a silent witness to her private suffering for too long. To stand back and do nothing would be contrary to everything we believe in.”
