The 1979 election ended an era of political consensus

In short: Before 1979, British politics operated under a settled agreement: a mixed economy, full employment, and a central role for trade unions. This 'post-War settlement' was so stable that neither major party dared to challenge it—until the winter of discontent shattered the social contract and paved the way for a radical shift.

The General Election of 1979 did more than just swap one party for another; it inaugurated what Professor Vernon Bogdanor describes as a 'sea-change' in British politics. It marked the end of the post-War settlement, a period following 1945 where certain economic and social structures were considered closed to debate. This consensus included a mixed economy featuring a nationalized sector alongside private enterprise, which both Labour and Conservative parties had accepted until that pivotal year.

Central to this old order was the commitment to full employment. Until 1979, no party dared to break from the belief that the state should secure full employment through broadly Keynesian policies of demand management and economic fine-tuning. Furthermore, since the early 1960s under Harold Macmillan, both parties agreed on an 'incomes policy'—either voluntary or statutory—and maintained a system where trade unions were treated as an 'estate of the realm,' entitled to consultation on major domestic policies.

The collapse of this consensus was accelerated by the 'winter of discontent,' characterized by public sector strikes that effectively destroyed the Labour government's social contract. The resulting election saw the largest swing since World War II, exceeding 5%. It ushered in an 18-year period of Conservative rule—the longest continuous premiership since Lord Liverpool (1812–27)—and fundamentally redefined the role of the State, moving away from the nationalized sectors and union-heavy structures that had defined Britain for decades.

This transition was not merely a change in leadership but a structural revolution. The 1979 victory indicated a transformation regarding governmental duties, transitioning towards a framework where public industries faced total removal or major downsizing by abandoning Keynesian oversight and post-War mixed economy pacts.
