In his account of Thatcherism as a hegemonic project, Stuart Hall points out that discourse theory provides insight both into the ways in which Thatcherism was constructed as a discourse from a combination of disparate ideological strands and into the ways in which this discourse was engaged in a hegemonic project. However, discourse analysis has rarely been applied in empirical study of the spread of the ideas and values of Thatcherism. The findings of attitude surveys indicate the failure of Thatcherism to produce radical social and cultural change. This paper presents textually oriented discourse analysis as an alternative way of understanding the spread of Thatcherism to that of attitude surveys. Research applying the approach demonstrates the continuing use of elements of Thatcherite discourse across the Conservative party and Labour party and hence the lasting impact of Thatcherism in spite of its failure to become hegemonic.
