This paper asks how ideas national Members of Parliament convey about parliamentary representation in the EMU change from the Eurozone crisis to the Covid-19 crisis, and how we can understand this evolution. The paper examines the parliamentary adaptation to the European Semester in the lower chambers of France and Germany through interviews, as well as the parliamentary debates at the occasion of important steps for the evolution of the EMU through a qualitative discourse-analysis. The paper argues that attention to modes of parliamentary participation can be understood by the degree of institutionalisation of the European budgetary exercise and parliamentary roles as played in practice on domestic level.
