ABSTRACT
This chapter discusses the dependent variable – the UK political system – focusing specifically on its Europeanisation. In principle, the idea of “Brexit as a process” could be challenged and rejected, for instance, by conceiving Brexit to be a distinct event that occurred at midnight on 31 January 2020. Brexit had an impact on a political system which was already under strain in several respects before the prospect of leaving the EU entered the policy-making agenda. A different stream of the Europeanisation literature has instead focused on political parties and party systems. Brexit can be seen as a shock altering the politico-institutional equilibrium. The political system would be characterised by more devolution and the weakening of centrifugal tendencies.
