The Reign of King Charles III: Anticipation and Expectations.

In the event of King Charles's death, the Operation Menai Bridge contingency plan would kick in, with preparations for his formal state funeral starting almost immediately. The new monarch would automatically inherit the throne, with Prince William next in line. Camilla, as a spouse who married into the royal family, cannot inherit the hereditary title and would not be able to keep her title of Queen Consort. She could take the role of queen-dowager, but it's not yet known if she would use that moniker. Prince Harry would probably become Regent until Prince George is old enough to carry out the roles of a constitutional monarch.
