The British Labour Party is in crisis. A prolonged period of government between 1997 and 2010 saw the party intellectually exhausted. The subsequent leadership of Ed Miliband ultimately failed with the loss of the 2015 General Election, and the party now finds itself without a clearly defined set of aims and values. Rebuilding Social Democracy is the first major reappraisal of social democracy and thinking on the centre left since the election of Jeremy Corbyn. With a foreword by Peter Hain, it examines the key foundational principles of social democracy, including economic reform, equality, welfare, public service organisation, social cohesion, civil liberties, democratisation, and internationalism, in order to find a route back to political credibility for Labour. Written by leading academics in the field, it identifies the values and objectives needed to move the party forward, and revive left and centre-left thought and practice in Britain as an alternative to Conservative austerity.
