Meghan Markle's 'Graceless' Behaviour Would Have 'Appalled' Princess Diana - Royal Biographer

Meghan Markle and Prince Harry's 'graceless' behaviour would have 'appalled' the late Princess Diana, according to Lady Colin Campbell.

The royal biographer, 69, who has published three books about the British Royal Family, claimed the Duke, 34, and Duchess of Sussex, 38, 'trot out the charm when it suits them' but are 'otherwise graceless'. 

She went on to slam Meghan's behaviour as showing a 'lack of understanding and appreciation' of her royal position.
