I have only just spotted and listened to Tristram Hunt's radio programme about 'The Middle Way' in his brief series Ideas - The British Version. It was broadcast last Sunday and will only be available on the 'Listen again' facility for another 24 hours or so.
It deals with attempts in the early 20th century to develop progressive alternatives to Marxist communism and laissez-faire Liberalism. It touches on New Liberalism, Keynesianism and Fabianism, dealing with their influence on British and continental politics.
I'm not a huge fan of Tristram Hunt and perhaps the programme is a touch simplistic. But New Liberalism does not often feature on Radio Programmes - even the rarified airwaves of Radio 3. So it's well worth a listen.
