At a time of significant structural change, the UK’s constitutional and political arrangements face unprecedented challenges. There are strong arguments to be made for increasing the level of scrutiny of constitutional reform by accountable bodies, particularly through the vehicle of the Parliamentary Select Committee. Yet, the number of Committees tasked with examining constitutional matters has decreased; in particular, the Commons Political and Constitutional Reform Committee was not re-appointed following the 2015 General Election. Drawing on a detailed case study of the work of this unique committee, Dr Eloise Ellis examines the implications of its dissolution for the parliamentary scrutiny of constitutional reform more broadly.
