Meghan, Duchess of Sussex has taken the unusual decision to sue the publisher of the Mail on Sunday after the newspaper published a handwritten letter she had sent to her estranged father.

n a statement, the Duke of Sussex said he and Meghan were forced to take action against “relentless propaganda”.

Prince Harry said: “I lost my mother and now I watch my wife falling victim to the same powerful forces.”

A Mail on Sunday spokesman said the paper stands by the story it published and will defend the case “vigorously”.

Law firm Schillings, acting for the duchess, accused the paper of a campaign of false, derogatory stories.

The firm has filed a High Court claim against the paper and its parent company over the alleged misuse of private information, infringement of copyright and breach of the Data Protection Act 2018.
