This report studies sexism and gender-based violence in European parliaments. The survey’s findings are based on interviews with 123 female members of parliaments (MPs) and parliamentary staff from 45 European countries. Results show that sexism, abuses of power and (online) psychological, physical and sexual violence against women in parliaments exist in all the Council of Europe’s member States. For example, 85.2 per cent of female MPs said they suffered psychological violence in the course of their parliamentary career. The study calls on parliaments and parliamentarians to take action on these issues, such as implementing laws to combat violence against women and promoting a gender- and equality-sensitive culture in parliament.
