Demographic and political components in the decline of British class voting 1964–1979

The weakening of the British class alignment since the early 1960s has been extensively documented in past research. This article seeks to identify components contributing to the extent of class alignment, so as to clarify what is that has declined, and when; and to speculate about the reasons for the decline and its implications for the future of the British party system. In fact only one component shows any systematic change over a fifteen year period, and this change can be placed quite specifically between 1966 and 1970. Several more recent events in British politics appear to have causes that can be traced to this original change.
