The announcement of the planned litigation comes after the Duke and Duchess of Sussex said earlier this week they would sue the Mail
Britian's Prince Harry is expected to sue the publishers of Rupert Murdoch's Sun newspaper and the Daily Mirror over allegations of phone-hacking as he and his wife Meghan step up their battle with the tabloid press.
The move by Harry comes days after he and wife Meghan took legal action against the Mail over the publication of a private letter, allegedly to her father, that her lawyers said was quote "unlawful."
In an emotional statement earlier this week, Harry said the treatment of Meghan by sections of the British press was reminiscent of their approach to his mother Diana, who died in a car crash in 1997 after being followed through the streets of Paris by photographers.
He said in a statement QUOTE "My 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. I lost my mother and now I watch my wife falling victim to the same powerful forces."
Harry was one target in a phone-hacking scandal that rocked Murdoch's newspaper empire and prompted the closure of his News of the World tabloid in 2011.
The Duke and Dutchess of Sussex have just returned from a 10-day tour to South Africa he referred to as a "second home."
Visiting Africa over the years had helped him cope with the death of his mother.
