Of Prince Philip’s eight grandchildren, one will now receive particular attention. Prince Harry will be desperate to come back to Britain for his beloved grandfather’s funeral. In all the bombshell revelations of the Sussexes’ interview with Oprah Winfrey last month, his devotion to his grandparents was clear. “I’ve never blindsided my grandmother. I have too much respect for her,” Harry insisted. The Duchess added that, when she heard about the Duke of Edinburgh’s illness, “I just picked up the phone and I called the Queen just to check in.” Amid the subsequent furore over the couple’s claim that the colour of their son’s skin tone had been discussed by members of the family, Harry also acted in his grandparent’s defence. “He wanted to make sure I knew, and if I had an opportunity to share it, that it was not his grandmother or grandfather that were part of those conversations," Winfrey later revealed. That interview showed, then, what a central figure Prince Philip was in his grandson’s life, even thousands of miles away in Los Angeles. Indeed, of all the royal roles he has now relinquished for his new life in California, the one closest to his heart was as the Captain General Royal Marines – the ceremonial head of the Royal Marines. Prince Philip was Captain for an astonishing 64 years from 1953 to 2017, before relinquishing the role for Harry, who lasted just over three years. As well as being a grandfather to the nation, the Duke of Edinburgh was a deeply attentive grandfather to his grandchildren – whatever their difficulties and however badly their parents’ marriages fared. The latest evidence of that mutual grandparental affection came only this year. In March, Zara Phillips named her newborn Lucas Philip Tindall. While in February, Princess Eugenie and Jack Brooksbank called their son August Philip Hawke Brooksbank after their treasured grandfather.
