In Spare and subsequent interviews, Harry argued that Charlotte and Louis, like him, would be considered “spares” rather than heirs, and therefore less important than the firstborn destined for the throne. He also expressed concern that their lives could be negatively shaped by that role.

Promoting his memoir in an interview with The Telegraph, Harry said, “Though William and I have talked about it once or twice, and he has made it very clear to me that his kids are not my responsibility, 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.”

While William and other members of the Royal Family have largely stayed silent about Harry’s remarks, one expert suggests the Prince of Wales would be unhappy with his brother discussing his children publicly.

Expert says William won’t appreciate it

Speaking to OK! Magazine, former BBC royal correspondent Jennie Bond said, “Harry has a huge chip on his shoulder about being a spare, we all know that now, but he doesn’t have to assume that William and Catherine’s children will feel the same as him.”
