To what extent does social media reinforce existing power arrangements of traditional political institutions or on the contrary, create a new scenario in which existing inequalities in parliamentary politics are reduced? This paper aims to compare MP's issue attention in the parliamentary arena and social media. We explain how MPs prioritize issues in two different institutional settings and explore the prevalence of gendered issues. Following existing research on agenda-setting, descriptive representation, and legislative careers, we argue that female MPs tend to occupy a marginal position in the political debate of a large set of issues in the parliamentary arena, especially those issues that are more rewarding in political terms. In contrast, female issue attention in social media is more diverse and linked to public opinion trends. These results apply regardless of the political party and the level of seniority. We use data from MPs in Spain between 2011 and 2018 comprising oral questions, tweets by MPs, and data on parties, parliaments, and the demographic features of MPs
