Meghan Markle, wife of Prince Harry, has begun legal proceedings against The Mail on Sunday for publishing a private letter in what her lawyers said was an "illegal" act.

Prince Harry said in a lengthy and influential statement yesterday that he and his wife had taken legal action in response to what he described as "bullying" by sections of the British press.

"Although this may not be a safe measure, it is the right one," Harry said.

"What scares me the most is that history is repeating itself. I have seen what happens when someone I love is turned into a commodity that is no longer treated or seen as a real person. "I lost my mother and now I see my wife falling victim to the same powerful forces."

His mother, Princess Diana, became one of the most haunted women on earth after she married a member of the royal family.

She died in a car crash in Paris in 1997 after being photographed by street photographers. Hundreds of millions of people around the world watched her funeral.

Prince Harry pointed out that the newspaper «misleading (readers) deliberately by deleting the scheme of selected paragraphs and specific phrases, and even certain words».

The Mail on Sunday denied the novel. A spokesman for the newspaper said it "adheres to the subject it has published and will defend this case strongly.

The 35-year-old prince, Queen Elizabeth's grandson and sixth in the throne, said the legal process "took several months to prepare."

He pointed to the "double standards" of some sectors of the popular press that write articles critical of the couple in the past months, but they are largely positive coverage of their current tour. “I was a silent witness to her suffering for a long time. "Silence and doing nothing will go against everything we believe in."
