To qualify, you must be British, an adult, and meet other rules. If the next in line is a minor or disqualified, it goes to the next eligible person.
For George to be next in line, his father, Prince William, would have to be out of the picture. If that happened before George was 18, Prince Harry would likely be Regent.
That’s because George’s younger sibs, Princess Charlotte and Prince Louis, would still be minors and not qualify. Harry, being over 18 and next in line after George and sibs, meets the criteria. His royal experience helps too. But his eligibility depends on things like legal residence.
In 2023, a palace source said William and Catherine were prepping George gently. They gave him a normal childhood but made sure he knew his future duties.
