Investigative journalist Tom Bower's explosive book 'Revenge: Meghan, Harry and the War between the Windsors' was released earlier this year and saw him unpick the truth behind the Sussexes by speaking to 80 people who know the couple personally.

Countless earth-shattering claims were made by the author, from how Meghan failed to get on with Harry's friends to the changes the palace forced the writers of Suits to make after the couple's relationship became public knowledge. However, one of the most interesting remarks came from the late Queen's Lady-in-Waiting, Lady Susan Hussey when she offered her view on Harry and Meghan's relationship ahead of their wedding in 2018.

Lady Susan is said to have made the comment a few months before the couple married at a lunch with a group of theatre executives.

Bower wrote: "While discussing the possibility that Meghan might become linked with the National Theatre after the wedding, Hussey became unexpectedly serious about the couple’s future. 'That will all end in tears,' she is alleged to have warned. 'Mark my words.'"

Lady Susan was a treasured member of the late Queen's inner circle and was widely considered to be one of her dearest friends.

When Prince William was born in 1982, the-then Prince and Princess of Wales chose to honour Lady Susan by making her one of William's godmothers.

Those also included in the line-up were King Constantine II of Greece, Princess Alexandra, The Duchess of Westminster, Norton Knatchbull, 3rd Earl Mountbatten of Burma and King Charles' mentor, Sir Laurens van der Post.
