Prince William and his wife Catherine have been strongly urged to keep eldest son Prince George away from uncle Prince Harry's "negative influence".
The Duke of Sussex's former biographer Angela Levin made the comments to OK Magazine, saying she doesn't want the second in line to the throne from repeating what she perceives to be Harry's mistakes.
"Kate and William are there to help him [George]," Levin said.
"But he needs to be kept away from Harry's negative influence.
"George doesn't have a dysfunctional family, unlike William and Harry growing up, so he should fare better. Kate and William are there to help him."
George is the eldest of Kate and William's three children - and Harry has already previously shared his concerns Louis and Charlotte could end up as spares to the monarchy, much as he did to older brother William.
In memoir Spare, Harry said it "worries me".
"I still feel a responsibility knowing that out of those three children, at least one will end up like me, the spare. And that hurts, that worries me," he wrote.
Levin's comments follow fellow royal author Tom Bower, who suggested George will be none the wiser of the true situation between his parents and uncle and the perceived rift between Harry, Meghan, William and Kate.
"Kate was the peacemaker between the brothers at the late Duke of Edinburgh's funeral [in 2021], but after the release of Harry's book and the Sussexes' documentary, that's all over. I really don't think Kate wants to see Harry again. Of course Prince George will be oblivious to all this - Harry will simply be forever marginalised in his memory," the New York Post quoted him as saying.
The Post also claimed King Charles is the only senior member of the royal family who maintains contact with Harry and his wife, Meghan Markle.
