Outlining the historical context, and offering suggestions for contemporary thinkers, this comprehensive overview shows how all three major UK political parties have made a significant contribution to the One Nation agenda over the past century and a half. Re-asserting the One Nation tradition inherent in interventionist liberals like Keynes and Lloyd George, it encourages us to look beyond reformist high Tory politicians such as Benjamin Disraeli and sketches out precedents for current politicians in areas such as house building, local government, the living wage, a financial transaction tax, and the welfare state.
