The post-war consensus, sometimes called the post-war compromise, was the economic order and social model of which the major political parties in post-war Britain shared a consensus supporting view, from the end of World War II in 1945 to the late-1970s. It was abandoned by Conservative Party leader Margaret Thatcher. Majorities in both parties agreed upon it. The consensus tolerated or encouraged nationalisation, strong trade unions, heavy regulation, high taxes, and a generous welfare state. There was a widespread consensus that covered support for a coherent package of policies that were developed in the 1930s and promised during the Second World War, focused on a mixed economy, Keynesianism, and a broad welfare state. In recent years, historians have debated the timing of the weakening and collapse of the consensus, including whether it ended before Thatcherism arrived in 1979. Origins of post-war consensus The thesis of post-war consensus was most fully developed by Paul Addison. The basic argument is that in the 1930s Liberal intellectuals led by John Maynard Keynes and William Beveridge developed a series of plans that became especially attractive as the wartime government promised a much better post-war Britain and saw the need to engage every sector of society. The foundations of the post-war consensus can be traced to the Beveridge Report. This was a report by William Beveridge, a Liberal economist who in 1942 formulated the concept of a more comprehensive welfare state in Great Britain. The report, in shortened terms, aimed to bring widespread reform to the United Kingdom and did so by identifying the "five giants on the road of reconstruction": "Want… Disease, Ignorance, Squalor and Idleness". In the report were labelled a number of recommendations: the appointment of a minister to control all the insurance schemes; a standard weekly payment by people in work as a contribution to the insurance fund; old age pensions, maternity grants, funeral grants, pensions for widows and for people injured at work; a new national health service to be established. The post-war consensus included a belief in Keynesian economics, a mixed economy with the nationalisation of major industries, the establishment of the National Health Service and the creation of the modern welfare state in Britain. The policies were instituted by all governments (both Labour and Conservative) in the post-war period. The consensus has been held to characterise British politics until the economic crises of the 1970s (see Secondary banking
