The Duke of Sussex has begun legal action against the owners of the Sun, the defunct News of the World, and the Daily Mirror, in relation to alleged phone-hacking.
Documents have been filed on behalf of Prince Harry over the alleged illegal interception of voicemail messages, Buckingham Palace has confirmed.
His wife Meghan recently launched legal action against the Mail on Sunday.
It is accused of unlawfully publishing a private letter to her father.
The BBC has not yet established when the duke’s allegations date from.
However, Jonny Dymond, the BBC’s royal correspondent, says: “The presumption is this goes back to the phone hacking scandal of the early 2000s.”
A spokeswoman for News Group Newspapers (NGN) – the publishers of the Sun and the News of The World – said: “We confirm that a claim has been issued by the Duke of Sussex.
“We have no further comment to make at the current time.”
The duke’s fresh legal claim comes just days after he accused the British tabloid press of “relentless propaganda” in his statement announcing his wife’s legal action.
In the statement, which was issued during the couple’s tour of southern Africa, Prince Harry said the “painful” impact of intrusive media coverage had forced the couple to take action.
Referring to his late mother Diana, Princess of Wales, the prince said his “deepest fear is history repeating itself”.
“I’ve seen what happens when someone I love is commoditised to the point that they are no longer treated or seen as a real person,” he said.
The details of the duke’s legal action were first reported by the website Byline.
