The Europeanization of the political class in the European Parliament: a cross-country and cross-temporal analysis of MEPs’ career patterns (1979-2019)

The European Parliament (EP)’s formal authority has considerably expanded since 1979. As a result, several studies have – conceptually and empirically – posited the development of a European political class over time. Since Scarrow (1997)’s seminal distinction between ‘EP careerists’, ‘domestic- oriented MEPs’, and ‘short-term politicians’, there has been surprisingly no systematic analysis, though. Studies are often country-oriented and/or restricted to some legislative terms. This paper presents the first systematic empirical analysis of all 3,654 MEPs’ career patterns from the 28 Member States over 40 years (1979-2019). Using Borchert’s (2011) analytical framework as a heuristic device, the paper analyses how the “attractiveness”, “accessibility” and “availability” of offices in the EP has shaped MEPs’ career patterns. The main conclusion is that the Europeanization of the political class is a distinctive trend and that it took place at an early stage of the institutional development of the EP. Furthermore, despite the recent rise of Euroscepticism, the professionalization of MEPs’ career has never been as large as in the latest legislative terms. Yet, EPGs do not contribute equally to the rise of this European political class. On the opposite, fragmentation of party systems in the late 2000s and early 2010s has questioned the (historical) contribution of some of the most influential EPGs. In this wake, the paper argues that these latest developments could undermine the EP’s formal policy-making capacity in the near future, as illustrated by the recent 2019 European elections (largest turnover and biggest electoral success of Eurosceptic parties).
