The Duchess of Sussex’s lawyers have denied she “collaborated” with the authors of a recent book about her and the Duke of Sussex at the latest hearing of her High Court action against the publisher of the Mail on Sunday.

Meghan is suing Associated Newspapers (ANL) over its publication of a “private and confidential” letter sent to her estranged father Thomas Markle in August 2018.

The Duchess, 39, claims the February 2019 publication of parts of the handwritten letter to Mr Markle, 76, was a misuse of her private information and breached the Data Protection Act.
