<p>Women in politics are targets of harassment, intimidation, and abuse. Violence affects women in all aspects of their life and parliaments are not immune to this problem. Beyond individual suffering, gender-based violence interfere with women’s right to participate in political life and undermines the representativeness of political institutions. What are parliamentary institutions of the EU and EU member-states doing to address this? Despite growing international recognition, the adoption of specific policies to tackle the issue within parliamentary institutions is insufficient. Drawing on a framework that combines the literature on public ethics regulation and feminist institutionalism, we compare the measures to prevent and detect gender-based violence in EU27 parliaments and the European Parliament. The data shows lack of recognition of the issue in almost half of the European parliaments. The variety of categories of parliamentary personnel and the complexity that results from differences in their legal status make internal parliamentary policies fragmented, with different procedures for different groups, and ultimately incomplete. Harassment is typically understood as a workplace hazard, rather than an issue of political equality and representation, with the vast majority of parliaments excluding members of parliament from their protective measures. The ideal of gender-sensitive parliaments is still far away.</p>
