Presidentialization and the politics of coalition: lessons from Germany and Britain

IntroduzioneIn this article, we seek to re-consider the ‘presidentialization of politics’ argument in the light of recent developments in Germany and the United Kingdom. The experiences of coalition government suggest prima faciegrounds for the erosion of the presidentialization process in each country. Germany has operated with a Grand Coalition in which domination of the executive by the Chancellor would seem less likely, whereas the long history of single-party governments in the United Kingdom gave way to a rare experiment in coalitional power sharing between 2010 and 2015, circumstances which should limit prime ministerial power. However, it is our contention that the presidentialization thesis retains its purchase in these two countries. German Chancellors and British prime ministers have been increasingly able to mobilize power resources, which allow them to govern more independently of their own parties and their coalition partners, and this seems to hold across a variety of political circumstances.
