ABSTRACT This paper inductively distinguishes six types of European Parliament (EP) involvement in the negotiation of international agreements. Since 2009, the EP has veto power on international agreements and has leveraged it through various activities such as resolutions. However, there exists no cross-case characterization of the EP’s involvement. Therefore, this paper asks: what are the types of EP involvement during the negotiation of international agreements? To systematically compare the nature, frequency and timing of EP activities, sequence analysis is applied to a dataset of EP activities relative to the 344 agreements concluded since 2009. For a majority of agreements, the EP acts as a ‘bystander’ and does not conduct any activities. When it does conduct activities, the EP most frequently acts as a ‘loud late riser’ and is active only during the ratification stage. For other agreements, EP involvement is very diverse regarding the timing and frequency of activities.
