Court politics is about who in British government did what to whom, when, how, why, and with what consequences. In The Prime Ministerial Court Rod Rhodes provides a thorough depiction of the court politics of the Conservative governments of the twenty-first century, namely the courts of David Cameron, Theresa May, and Boris Johnson. Exploring specific topics, including the courtiers, the prime minister's craft, reshuffles, resignations, and leadership challenges, and the political games and feuds in the court between ministers, advisers, and civil servants, Rhodes concludes that the British government has a new Establishment in which the skills of 'knavery' abound. He finds evidence of betrayal, revenge, lying, scandals, and bullying with such machinations oiled by gossip, humour, and alcohol. Analysing the everyday practice of the 'dark arts' by the British political and administrative elite, each chapter includes a short case study of the court in action, covering the education wars, the 2018 election, and the Covid-19 crisis. Each case illustrates the personal, electoral, and governmental consequences of court politics. Rhodes warns that there are more and more knaves, decency is in decline, and British government needs 'rules for rulers'. Above all, he cautions citizens - 'beware, here be dragons'.
