The European Parliament (EP) as one of the key institutions of the European Union has gained considerable powers over time and often presents itself as a constant gender equality promoter. Whilst gender equality in the EP tended to be analysed in terms of women's descriptive, substantive and symbolic representation, this article shifts the focus to the concept of power itself in assessing gender equality achievements in and through the EP. Applying Amy Allen's conceptualization of power as power to, power over and power with to a critical reading of recent literature, it explores who can exercise power over what in the EP and the consequences for gender equality. The article challenges the EP as a unified gender equality actor and highlights its highly gendered nature in which power over and power to are intertwined, with power to occurring without power over and power with unfolding through alliances and coalitions.
