How (not) to form a progressive alliance : lessons from the history of left cooperation

Abstract

Britain's political parties can be divided into two blocs : a 'progressive bloc' of parties on the left/centre-left, and a 'reactionary bloc' of those on the right/centre-right. In three of the last four general elections, the progressive bloc won an appreciably larger share of the popular vote than its reactionary rival. Yet its greater internal fragmentation has been repeatedly punished under first past the post, leading to what is now over a decade of Conservative-led governments. This has prompted growing pressure to form a 'progressive alliance' between Labour, Liberal Democrats, Greens, and their Scottish, Welsh and Northern Irish nationalist competitors. This article sheds a historical and international light on these demands, examining the difficulties other similar efforts at progressive cooperation have faced across the world. It considers how progressive alliances have previously sought to overcome geographical, ideological, and social divides between their constituent members, and draws some salutary lessons for British progressives today.
