Andrew Marr's History Of Modern Britain

Episode Three

Paradise Lost, 1964 - 1979

As the 1960s progress, Harold Wilson takes centre stage in a rapidly changing Britain as the country looks to modern technology and a fairer, liberated future. However, the Wilson governments presided over years of industrial conflict, stagnation and decline. As Edward Heath's government ascends to power in the 1970s, British industry is reduced to working a three-day week, electricity is rationed and the country is again haunted by the shadow of wartime austerity.
