Influencing the heads of state and government : Europarty influence in the European Council, in the light of the Spitzenkandidaten-processes in 2014 and 2019.

Abstract: This study aims to contribute to the debate on the influence of Europarties in the European Union decision-making process, and more precisely in the European Council. As a starting point the theory on Europarty influence in the European Council, by Jonas Tallberg and Karl Magnus Johansson, will be tested in order to assess its validity. There is a need to further research the role of the Europarties in the decision-making processes of the European Union, since the contributions to the field are scarce. The theory suggests that Europarties can be expected to be influential when 1) there is ideological polarisation surrounding the question of concern, 2) one party is dominating the European Council, and 3) when a Europarty is successful in mobilising and creating cohesion among its leaders. In addition, the Europarties have to be able to compete with domestic constraints that the members of the Council are bound by. The theory is empirically tested by a comparative case study on the outcomes of the Spitzenkandidaten-processes in the European elections in 2014 and 2019. It seems that the Europarties were influential and managed to get a Spitzenkandidat elected as Commission President in 2014, but less successful in 2019. However, the findings of the empirical study suggest that the Europarties were successful in mobilising support also in 2019, but a chain of events led to the fall of the Spitzenkandidaten-process in its current shape and the Europarties have most likely lost a part of their long-term influence.
