Recent debates within the gender and politics field have reflected a shift to consider how, when, where, why and by whom the representation of women's interests occurs (Lovenduski 2008). Indeed, Celis et al. have suggested that those who seek to act on behalf of women may not necessarily be female (2008). This possibility is significant and requires both conceptual and empirical analysis. This article begins this process by adopting a case study approach to comparing the ways in which men and women MPs articulate women's interests.
