Prince William is currently third in line with the throne, and will be heir to the throne when Queen Elizabeth II dies and Prince Charles becomes king. William has known that he will become king of England one day at a time, dating back to the early stages of his childhood. Prince Harry, on the other hand, is very unlikely to take up that position, with his brother, Prince George, Princess Charlotte and Prince Louis combining to make him sixth in line with the throne.
This is a fact. Prince Harry is also believed to have known since he was just a child, as a princess Diana insider claims that he would bother his older brother about what role he would one day fill.
Princess Diana's former protection officer Ken Wharfe talks about "Robert Jobson's Royal Podcast" in 2018 claiming that young prince Harry would tell William that he could do "everything he wants".
Inspector Wharfe then remembered a car trip when the boys were just children.
With his nanny and late princess Diana in the vehicle, Harry turned to his older brother and bothered: "It's okay, I can do something because I do not want to be king. You will be, therefore I can do what I want."
Inspector Wharfe believes that William "gladly enjoyed" the recognition Harry had given him his place in the family.
Ken said William was pleased that it was "a confirmation that at least his brother knew he would be king."
He added: "As a child, I always thought it was quite fun."
While William is likely to become king, Ken added to the podcast that Princess Diana also thought Harry would make a good king.
Diana is said to have nicknamed her youngest son "Good King Harry" in her youth.
"Many, including Diana, believed that Harry – given his predilection to be quite robust and good to take orders would have made a good king himself," explained Ken.
