This book explores the nature of electoral change in Britain during the last half century. The period from 1945-70 was the classic era of two-party dominance at every level of British politics: at Westminster, county hall, and in the electorate. Since the early seventies Conservative and Labour hegemony has remained virtually unaltered in Parliament, but their grip has been loosened in local government, and the popular foundations of the two-party system have been eroded among voters. Why has Britain evolved from a dominant to a declining two-party system during the last fifty years? This study considers alternative explanations for these developments, focusing on changes in voters, parties, and political communications. The book provides students with a fresh and accessible perspective on theories of electoral change, placing developments in Britain within their broader comparative context, and challenging many conventional assumptions about trends in voting behaviour.

Nobody doubts that politicians ought to fulfil their promises – what people cannot agree about is what this means in practice. The purpose of this book is to explore this issue through a series of case studies. It shows how the British model of politics has changed since the early twentieth century when electioneering was based on the articulation of principles which, it was expected, might well be adapted once the party or politician that promoted them took office. Thereafter manifestos became increasingly central to electoral politics and to the practice of governing, and this has been especially the case since 1945. Parties were now expected to outline in detail what they would do in office and explain how the policies would be paid for. Brexit has complicated this process, with the ‘will of the people’ as supposedly expressed in the 2016 referendum result clashing with the conventional role of the election manifesto as offering a mandate for action.

This book explores the new politics of class in 21st century Britain. It shows how the changing shape of the class structure since 1945 has led political parties to change, which has both reduced class voting and increased class non-voting. This argument is developed in three stages. The first is to show that there has been enormous social continuity in class divisions. The authors demonstrate this using extensive evidence on class and educational inequality, perceptions of inequality, identity and awareness, and political attitudes over more than fifty years. The second stage is to show that there has been enormous political change in response to changing class sizes. Party policies, politicians' rhetoric, and the social composition of political elites have radically altered. Parties offer similar policies, appeal less to specific classes, and are populated by people from more similar backgrounds. Simultaneously the mass media have stopped talking about the politics of class. The third stage is to show that these political changes have had three major consequences. First, as Labour and the Conservatives became more similar, class differences in party preferences disappeared. Second, new parties, most notably UKIP, have taken working class voters from the mainstream parties. Third, and most importantly, the lack of choice offered by the mainstream parties has led to a huge increase in class-based abstention from voting. Working class people have become much less likely to vote. In that sense, Britain appears to have followed the US down a path of working class political exclusion, ultimately undermining the representativeness of our democracy. They conclude with a discussion of the Brexit referendum and the role that working class alienation played in its historic outcome.
