Replication Data for: When politicisation meets ideology: the European Parliament and Free Trade Agreements

Since the Lisbon Treaty, the European Parliament (EP) has considerably increased its competencies in European Union (EU) trade policy. At the same time, a “new generation” of Free Trade Agreements (FTA), including the TTIP with the United States, CETA with Canada and the agreement with Japan, have been negotiated by the European Commission. Whereas existing literature has tackled the process of the EP's institutional self-empowerment in this policy area, there is no systematic research investigating the lines of conflict within the EP over FTAs. Through a newly collected dataset of all EP plenary debates between 2009 and 2019 on six relevant FTAs, we extract MEPs preferences by means of a manual textual analysis. We then test the explanatory power of the two traditional lines of cleavages within the EP over MEPs stated preferences: position on the left-right axis and support for EU integration. We find that both these dimensions fundamentally shape the conflict in the EP over FTAs. The impact of these two ideological cleavages is magnified in the context of politicised FTAs, namely the TTIP and CETA. Through these findings, the article significantly contributes to the research on competition in the EP and, more broadly, to the understanding of EU trade policy and its emerging politicisation dynamics.
