Charles [Tim Pigott-Smith] gathers with his family after the funeral of Queen Elizabeth II, stepping into the throne with a measured, wary authority. As the new king, he holds his first weekly audience with Prime Minister Tristram Evans [Adam James], and they spar over a controversial Bill for the statutory regulation of the press, which has cleared both Houses and awaits royal assent. Charles fears the measure could curb press freedom and impede uncovering abuse of power, and he asks for alterations, but the PM refuses.
Meanwhile, Mrs Stevens [Priyanga Burford], the Leader of the Opposition, arrives for a weekly audience with the king, a new ritual Charles has introduced. She questions the bill’s purpose and, despite reminding Charles of his power, concludes there is little alternative but for him to sign. The tension in the room sets the stage for a broader clash between royal prerogative and democratic process.
In parallel, Prince Harry [Richard Goulding] begins a romance with Jess Edwards [Tamara Lawrance], a working‑class republican who makes him rethink his place in the royal fold. Jess later approaches royal press adviser James Reiss [Tim McMullan] about an ex‑boyfriend who threatens to leak compromising photographs, a development she fears could damage both her and Harry’s reputations and threaten the couple’s future.
Both Charles and William [Oliver Chris] have already encountered the ghost of Princess Diana [Katie Brayben], who promises to guide them toward becoming “the greatest king of all.” The eerie visitation underscores a mounting sense of destiny and duty that will soon collide with political reality and public scrutiny.
One of Charles’s first actions is to refuse royal assent to the press regulation bill. The Prime Minister then convenes a crisis meeting with the Opposition and later tries to persuade the king to sign, but Charles remains resolute. Evans threatens to push the law through bypassing royal assent, and the pressure grows as the clock ticks toward a vote.
Before any vote can take place, Charles uses his royal prerogative to dissolve Parliament, blocking both paths and throwing the government into disarray. The Speaker of the House of Commons, Douglas Rowe, reluctantly supports the king and prevents Parliament from reassembling, further destabilizing the political landscape.
Protests erupt across the country, with the most violent clashes in London. In response, Charles tightens the army’s presence around Buckingham Palace, a move that only heightens public tension. He also offers royal protection to Jess and agrees to Harry’s wish to become a commoner so he can pursue a life with her.
Facing mounting backlash, Evans seeks a way to salvage the situation by turning to the Waleses. He asks William and Catherine to mediate between Parliament and the Crown, a proposal Catherine [Charlotte Riley] makes possible by advocating a plan that could restore order: William would act as a mediator between Parliament and his father. The announcement is delivered in a press conference with marked compromise, though it fractures trust within the family.
The shock waves continue as Charles confronts his son and James Reiss in a tense, unresolved standoff. In a pointed exchange, William questions his father’s handling of Diana’s memory and presses him to abdicate to help restore order and public confidence.
Catherine and Harry deliver a blunt ultimatum: they will step away from Charles and his life if he does not step down. Reluctantly, Charles abdicates in favor of William, who intends to sign the press bill and restore a balance between the monarchy and Parliament.
Before the joint coronation at Westminster Abbey, Harry meets with Jess and reluctantly tells her they cannot continue as a couple, acknowledging that their plans would upset the delicate status quo now that a new king is in place. The film closes on a ceremonial note, as William and Kate’s coronation as king and queen consort unfolds.
In the moment of crowning, Charles—unseen by the Archbishop of Canterbury—places the crown on his son’s head and exits, while the crowd erupts in a chorus of approval and defiance. > God Save the King
