King Charles III is a stage play that examines the modern relationship between the monarchy and democracy in England through a fictional imagining of Prince Charles's reign after the passing of Queen Elizabeth II. Shortly after the Queen's funeral, Charles holds his first weekly audience with the Prime Minister, during which they discuss a new bill to regulate the press. He and Parliament clash over the piece of legislation as he struggles with the morality of the bill and whether it restricts freedom of speech too harshly. A historic depiction of the future, King Charles III offers a controversial yet viable illustration of the unwritten rules of democracy and the relationship between Head of State and Head of Government.
