Charles and his family gather following the funeral of Queen Elizabeth II. Charles, as the new king, then holds his first weekly audience with the Prime Minister. They discuss a new Bill for statutory regulation of the press, which has passed the House of Commons and the House of Lords and awaits only Charles's royal assent to become law. Charles is concerned that the law restricts freedom of the press too much, and would allow governments to censor the news and prevent legitimate uncovering of abuse of power by the government. He asks the Prime Minister for alterations to the bill, but the Prime Minister refuses. The two men spar, as the Leader of the Opposition arrives for a weekly meeting with Charles, an innovation the new king has introduced. The Leader of the Opposition expresses his own doubts on the bill, but he sees little alternative but for Charles to sign. In parallel, Prince Harry has begun a relationship with Jess Edwards, a republican. Both Charles and Prince William have seen the ghost of Princess Diana, promising each man that he will become "the greatest king of all". One of his first actions is to refuse to give royal assent to the press regulation bill. The Prime Minister holds a crisis meeting with the Leader of the Opposition and then goes alone to try to convince Charles to sign, but Charles continues to refuse. The Prime Minister then threatens to pass a new law bypassing the royal assent and then pass the press law, but Charles then dissolves Parliament before the Prime Minister can bring either of these plans into effect. Protests begin across the country and especially in London. Charles increases the army guard at Buckingham Palace, offers his protection to Jess, and agrees to Harry's wish to become a commoner. The Duchess of Cambridge proposes a solution: William will serve as a mediator between Parliament and his father. William announces this plan at a press conference without his father's knowledge or consent. Seeing this as a betrayal, Charles reacts angrily. Ultimately, Charles is forced to abdicate in favour of William, who plans to sign the press bill and restore the status quo between king and Parliament. The play concludes with Harry's rejection of Jess, and William and Kate's coronation as king and queen consort.
Critical reception
The London and Broadway productions have both received positive reviews. The Telegraphs review on this play says, “attendance is compulsory’. It is said this is the best playwright work Mike Barlett has done yet. The thrills and plot twists of the play should remain a secret to those who have not been exposed yet to the reading. The Globe and Mail called the play "dreary" despite its success in London and on Broadway. It is explained to be a Shakespearean-like play that has already passed its “best before” date. The author talks about how some aspects in this futuristic play came true, like how Prince Harry ends up happy with his new spouse Megan Markle. There is also how the real Prince Charles is known to be involved with government issues and having strong opinions.
The stage play was adapted into a radio play for BBC Radio 3's Drama on 3 and broadcast 12 July 2015, starring the cast of the original West End production. It was re-broadcast on 6 November 2016, again on BBC Radio 3.
TV film adaptation
The play was adapted into a 90-minute TV film for BBC Two and Masterpiece on PBS. The adaptation first aired on BBC Two on 10 May 2017. Before the film had even aired, politicians and biographers already did not like the idea of a non-fiction futuristic world without the Queen. After viewing the play as a whole, it was seen as more of a political thriller and tragedy. The TV film is an hour shorter than the play time due to a few parts being removed from the original script.
