This book provides an original argument that rejects the idea of national MPs having but one ‘standard’ mode of representation. It acknowledges the national electoral connection, but considers representation beyond national borders. The author empirically investigates such patterns of representation in MPs’ parliamentary speech-making behavior and their attitudes in Austria, Germany, Ireland and the UK. The book analyzes representative claims in parliamentary debates on the Constitutional Treaty, the Lisbon Treaty and the Eurozone crisis, and relies on qualitative interviews with members of the European affairs and budget committees. It finds a Eurosceptic Europeanization in that national MPs from the Eurosceptic left particularly represent other EU citizens.
