Direct answer: Prince William is the heir apparent and would succeed King Charles III, followed by William’s children in the line of succession. If Charles were to pass, William would become king, Camilla would continue as Queen Consort, and the next in line after William would be his eldest child, Prince George, with the line continuing through George’s siblings in birth order (Louis and then Charlotte, depending on the order of birth and any changes to succession rules). This order reflects the current established rules of succession to the British throne.
