Andrew Marr's History Of Modern Britain

Episode One

Advance Britannia, 1945 - 1955

Britain in 1945; the country is victorious but nearly bankrupt. As Clement Attlee's Labour government sets out to build 'New Jerusalem', Britain is forced to hold out the begging bowl in Washington. Though Ealing Studios produces a series of very British comedies and there is a spirit of hope in the air, the British people's growing impatience with austerity threatens to take the country from bankruptcy to self-destruction.
