King Charles was reportedly left "crushed" by son Prince Harry, a pair of royal authors have revealed.
The Duke of Sussex allegedly gave his father just 20 minutes notice before he made the relationship with Meghan Markle public, reports the Mirror.
The new King, who was the Prince of Wales at the time, had been preparing to meet the King of Bahrain in November 2016, during a tentative tour of the Persian Gulf sovereign state.
