The Duke of Sussex entitled his memoir Spare as he is second to William in line to the throne and now a royal expert has told how Princess Diana was worried about his sense of “inadequacy” as a child

Prince Harry had a “feeling of inadequacy” compared to William even as a young child that concerned Diana, a royal expert has claimed.

The Duke of Sussex has had a frictious relationship with the Royal Family since leaving for the United States where he has been critical of his previous way of life in interviews with American media.

And in his memoir titled Spare he discussed his upbringing where he was given the nickname that was the title of the book by his father Charles. Harry claimed Charles said to Princess Diana: “Wonderful! Now you’ve given me an heir and a spare – my work is done.”

In the book he expresses his resentment to the nickname and the way he would always be playing second fiddle to William as he writes about his childhood and royal role.
