Labour, left and right: on party positioning and policy reasoning

Since the Second World War, the Labour Party has alternated between periods in which it has been positioned further to the left and others when it has been further to the right. The standard explanation for those oscillations is electoral–ideological. Labour moves to the right (towards the political centre) when it prioritises electoral considerations, usually after a period in opposition. It moves to the left when it prioritises ideology, usually after periods in government. Against this we propose a political economy–policy explanation. Labour moves to the right and a redistributive economic strategy when the economy is performing reasonably well. It moves to the left and adopts a structural economic reform programme when the economy is perceived to be in crisis. We argue that the political economy–policy explanation offers a more satisfactory account of when and why Labour has changed its spatial policy positioning in this period. By acknowledging the role of what we term ‘policy reasoning’ in the processes by which political parties (and the public) adopt and change spatial policy positions, our approach provides an alternative to the mechanistic models deriving from Downsian rational choice theory. It suggests that, contrary to general expectation, the Labour Party under Keir Starmer does not need to react to its 2019 election defeat by shifting significantly to the right
