For more than a decade, the most decisive influence on the empirical study of the British class structure has been the three consecutive electoral victories of the Conservative Party during the 1950s. The widespread belief that these events reflected some underlying change in the stratification of British society stimulated a new examination of the political attitudes and behaviour of the working class. In sociology this led to the exploration of the ‘embourgeoisement’ thesis culminating in the ‘affluent worker’ study by Goldthorpe and his colleagues and it is, perhaps, a comment on the state of sociological research into the British class structure that this study, together with its associated papers, remains the centre around which much of the debate on social stratification in contemporary Britain continues to revolve. In political science, however, the investigation took a different track. Instead of seeking an explanation of the Conservative electoral successes in terms of the working class becoming more middle class, political scientists sought an explanation in terms of increased working-class ‘deference’. Bagehot was enthusiastically resurrected (a new edition of The English Constitution appeared in 1963), and a spate of studies attempted to assess the ‘deferential’ component of English political culture.
