Andrew Morton, author of the most famous book on Princess Diana, says Meghan Markle holds a very important key for Royal Family's image.
Morton tells us Meghan becoming a Duchess after marrying Prince Harry is a much-needed step forward for the Royals after a checkered past where issues of race are concerned.
He says Meghan won't have to go around "kicking shins" to impart a sense of change at Kensington or Buckingham Palace -- her presence alone will do the trick.
Morton just wrote a new biography, "Meghan: A Hollywood Princess" ... and he'll have much more to say about her in next week's "Spilling Royal Tea" podcast. Meanwhile, check out this week's episode.
