Issues of diversity in elected bodies have been highlighted in recent years, both with regard to elected representatives themselves, and, more recently, in respect of the treatment of those working in such institutions, especially women. This article focuses on another aspect of diversity, inequality and representation, the voices heard by parliamentary committees in their scrutiny of government actions and legislation.

The article discusses the current position in the Scottish Parliament (and other UK legislatures) with, for example, around three-fifths of witnesses at Holyrood being male, and highlights both ‘demand’ and ‘supply’ factors that influence the make-up of committee witnesses. It also identifies a number of functions that witnesses can play for committees, and how these relate to diversity and representation, and suggests that there may be benefits to committees and legislatures in hearing from a wider range of voices.

Although there has been extensive research on electoral system choice at the national level, we know relatively little about the dynamics of deciding the rules of the game for sub-state institutions. This article examines the factors that influenced the choice of a proportional electoral system for the new Scottish Parliament in 1999. Through the use of archival sources and interviews with key participants, we challenge the conventional rational choice explanation for the adoption of the mixed-member proportional (MMP) system. Although rational considerations on the part of the Labour Party were involved in the choice of MMP, our findings suggest that, as at the national level, theories of electoral system choice need to consider normative values as well.
