The Duke of Edinburgh died aged 99 in April and was the longest serving royal consort. According to The Sun, Prince Philip left an estimated £30 million in his will when he died just weeks before his 100th birthday.

A royal insider told the publication the Duke honoured the “three key men in his life by leaving them money in his will”.

The majority of Philip’s estate is likely to go to his wife, Queen Elizabeth II.

But the source claimed the Duke has also rewarded his closest aides.

They told The Sun: “Unlike some other royals, Prince Philip will be generous to the three men who looked after him.

The source also claimed that Philip’s grandchildren, including Prince Harry, will have been “sorted out quite a while ago” in terms of money.

Prince Harry has been criticised for recent public comments on his experience of being a senior royal.

The source said: “Philip was not the sort of character to punish a grandson [Harry] for misbehaving.

“He was a very fair, even-handed and lovely man. Never held a grudge.”

A Buckingham Palace spokesperson told The Sun: “This is a personal matter for the family and as such arrangements are private.”
