Lady Colin Campbell claims Meghan Markle’s ‘graceless’ behaviour would have ‘appalled’ Princess Diana – and says it shows a ‘lack of understanding’ of her royal position

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.

Speaking to Woman magazine, the Jamaican-born socialite said: ‘Diana would be appalled, she had enough nous to know when to put on a show.

‘She was very aware of how important it was to be gracious, while Meghan – and Harry to an extent – trot out the charm when it suits them, but otherwise are graceless.’

She added: ‘Her behaviour shows a lack of understanding and appreciation of what being royal is. I’m not sure who she thinks she is behaving this way.’

Lady Colin also went on to claim Meghan and Harry are ‘depriving’ royal fans by being ‘pretentious’.

It comes just days after she warned Meghan can’t ‘hustle her way to the top’ as she did when she was an actress in Suits.

While she claimed she is ‘rooting’ for the Duchess, she also said she has an ‘awful feeling’ about her future if she doesn’t change her ways.

She told Good Morning Britain on Monday that Meghan needs to differentiate between how to behave as a celebrity and a member of the royal family.

Lady Colin said: ‘I have an awful feeling that Meghan needs to understand things she doesn’t yet understand.

‘Like there is a massive difference between being a celebrity, hustling your way from the bottom to the top, and she was a very proud hustler.

‘She used to use the word hustle for herself and her first husband, very proudly.’

‘Being a royal; you don’t hustle, the values, embodiment is completely different, she’s sorted, she’s got it, I think she needs to now embrace it and understand it’s a new game in town. She’s an actress, she needs to come up with a new act!’

And last month, Lady Colin hit out at Meghan for ‘acting like a celebrity’ by guest editing the September issuer of British Vogue.

She told Closer magazine: ‘She was never an A-lister, so she needs to stop acting like one.’

‘Royalty do not behave like celebrities do. It’s cheap, vulgar and irresponsible.’

The royal biographer, who claimed to be a confidante of Princess Diana, went on to say that Meghan was ‘letting down’ those who admire her by behaving in this way.
