Prince Harry is set to inherit a substantial sum from his great-grandmother, the Queen Mother, when he turns 40.

Prince Harry and Meghan Markle have been warned about “history repeating itself” by a royal expert who fears what the Queen Mother would make of their rift with the Royal Family, were she still alive.

This comes as Harry is due to inherit £7 million from his great-grandmother on his 40th birthday in September, as she set up a trust fund for him and Prince William before she died in 2002 aged 101. But former royal correspondent Jennie Bond believes the old family matriarch would not be happy with the way things have turned out for the Sussexes, particularly given her close bond with Harry.

She told OK! magazine: “The Queen Mother loved her great grandchildren…and they adored her sense of humour. She sometimes imitated Ali G, which William and Harry found hilarious. They had taught her how to do the voice and actions and, after lunch one day, she stood up and said to her daughter, the Queen: ‘Darling, lunch was marvellous – respec.’

“But I’m afraid the Queen Mother would have been mightily disappointed to see history repeating itself as Harry fell in love with a divorced American woman and then left royal life and went to live abroad… almost in exile, like her brother in law King Edward VIII, who abdicated for the love of Wallis Simpson.

“I think she would have been angry with Meghan for some of the things that she has said, and profoundly disappointed that Harry has publicly attacked his own family.”
