A court case brought by the Duchess of Sussex is about to start in London.

Meghan Markle's suing the Mail on Sunday for publishing parts of a letter she sent to her father,  complaining about his treatment of her.

UK Society of Editors executive director Ian Murray told Kate Hawkesby it's unusual for a member of the Royal Family to go to court over something.

He says she's obviously very upset and has a point to prove.
