Despite the tensions, Saturday’s funeral will almost certainly remind the brothers of their shared grief at another royal funeral more than two decades ago – when both of them walked behind their mother Princess Diana’s coffin as little boys in 1997.

On Saturday, Harry, 36, and William, 38, are due to join other high-ranking kings and walk behind their grandfather’s coffin as the funeral procession passes through Windsor Castle.

Many observers believe that Philip’s funeral will be an ideal opportunity for “The Firm” to show the world a unified front and for the royal brothers to ease tension. Philip, who had been married to Queen Elizabeth II for more than seven decades, died last week at the age of 99.

“They shared emotions. They currently share the grief over the death of their grandfather, “former Prime Minister John Major, who was appointed Guardian of the Princes after Diana’s death, told the BBC this week. “I very much hope that it is possible to repair any cracks that may exist.”

“I absolutely think it would be wrong to take care of yourself before the funeral. And I think it’s wrong to imagine that when so much has happened in the year and William has had so much more responsibility, they will pour out their hearts and hug each other, ”she told the AP.
