In this chapter, we take a close look at a predominant feature of UK democracy – Prime Minister’s Questions – the weekly parliamentary event, most notable for the showdown between the Prime Minister and his/her main political opponent, the Leader of the Opposition. We begin with an overview of PMQs, including claims it has descended into an event characterised by antagonistic political point-scoring. We then consider its history, including apparent changes – procedural and behavioural – revealed by systematic research. Subsequent sections focus on two forms of behaviour: adversarialism and equivocation. In the first, we see evidence in support of those views expressing concern that impoliteness, incivility and personal attacks are salient features of PMQs; however, certain circumstances or topics of debate can prompt relative politeness. The section on equivocation reveals that, compared with other forms of political discourse (e.g., broadcast interviews), PMQs has some of the highest levels of question evasion. Those findings have generated not only national news headlines, but were also cited in a question at PMQs. Finally, we consider public opinion; the weekly showdown is the prime psychodrama of British democracy, and because people either love it or hate it, PMQs has aptly earned the soubriquet of ‘political Marmite’.
