King Charles was left "crushed" after being told that Prince Harry's relationship with Meghan Markle would be made public just 20 minutes before it was widely announced, two royal authors have said.
The monarch, who was then Prince of Wales, was preparing to meet the King of Bahrain during a delicate tour in the Persian Gulf sovereign state in November 2016.
According to royal authors Omid Scobie and Carolyn Durand, who are thought to be close with the Duke and Duchess of Sussex, his team had spent months organising the tour, hoping it would be "covered significantly" by the media.
