Abstract
This chapter discusses the role of smaller parties in the law-making process. General elections in the UK are conducted with an electoral system which militates against the representation of smaller political parties, particularly those having no strong support at the regional level. However, events at Westminster over the last decade have increased the prominence of smaller parties in the operation of parliamentary business. The chapter first considers the role of small parties in the UK Parliament, committees and legislation, as well as their participation in backbench debates before examining how the political and electoral context of Parliament, especially in the twenty-first century, has affected the representation of smaller parties and the ways in which reforms to parliamentary procedure since the 1980s have enhanced the role of the second opposition party. It suggests that Parliament today offers more opportunities for smaller political parties to influence debate and policy, but this remains quite limited.
