Royal historian and author Gareth Russell claimed the Prince of Wales has “very different influences” which will make him “exciting” as a monarch.
Speaking on The Sun’s Royal Exclusive show, Gareth said it’s wrong for people to shoehorn “William as being Charles’s son” and “Harry as Diana’s son”.
The historian explained: “We sort of forget they have similarities to the other parent.
“William was immensely close to his mother and Diana was someone who was more of a radical royal compared to Elizabeth II.
“So he has these two very different influences and that I think makes them exciting as a future king.”
Gareth claims that Prince William will be “successful” if he embodies qualities from a number of Royal Family members.
He explained to The Sun’s Royal Editor Matt Wilkinson: “If he welds those two legacies – the willingness to change that Diana had and the enthusiasm for tradition Elizabeth II had – he could prove, I think, hugely successful as King William the fifth.”
This year has seen Prince William leading Royal Family duties, following King Charles and Kate Middleton being diagnosed with cancer.
William had temporarily cleared his diary to care for his wife Kate and their three children after she underwent abdominal surgery in January.
The Times reported that William wanted to “reassure the public” by stepping in.
All other working members of the Royal Family are understood to be continuing with public engagements in the King’s absence.
The Sun understands Charles and William have become incredibly close in recent months.
The King has been regularly staying at Windsor Castle on Sunday nights to spend time with his eldest son and heir to the throne.
