Meghan Markle's arrival on the royal scene after her engagement to Prince Harry was a "wake-up call" for the Prince and Princess of Wales, a new book has claimed.
After being welcomed into the royal fold, Meghan was quickly brought on board to join the Royal Foundation alongside her husband-to-be and her new in-laws William and Kate. Royal fans were delighted when the two couples, who were then dubbed the 'Fab Four', took part in their first engagement together. The foursome took part in a forum and Q&A session for the foundation, where they gave an update on their charitable projects.
