This article examines the problem of legitimacy within the EU political system and focuses on the political power and recognition of the only one directly elected EU institution – the European Parliament. Historically, being the weaker house of the EU legislative system, throughout the last decades, the European Parliament has increased the political authority dramatically. These political changes should have risen the participation of the EU citizens in the elections and the legitimacy of this EU institution. Analysing the Lithuanian case, based on the qualitative interviewing of politicians and quantitative survey of citizens, the authors claim that while most of Lithuanians recognise the significance of the European Parliament and the turnout in the European elections has increased, the European Parliamentary elections remain, however, of secondary importance.
