Meghan Markle has delivered a powerful “message” to the Princess of Wales amid rumours that King Charles has invited her and Prince Harry to Balmoral, according to a well-placed source. The insider speaking to Closer magazine, said the Duchess of Sussex would see any prospective royal gathering in Scotland as a symbolic victory.

The source told reporter Millie Payne: “To Meghan, this feels hugely symbolic. There was a time when it seemed unthinkable that she would ever be invited back to Balmoral or Buckingham Palace. It’s Meghan’s revenge on Kate, in a way. Her message to Kate is, ‘You’ll never win, and you can’t keep us out.’ Meghan believes she now holds all the cards.”
