Explaining the ‘quiet earthquake’: voting behaviour in the first election to the National Assembly for Wales

Abstract

This paper examines voting behaviour in the inaugural election to the National Assembly for Wales (NAW), held in May 1999. We address two questions: (i) why did the election produce a ‘quiet earthquake’ in Welsh electoral politics, with the nationalist Plaid Cymru denying the Labour party their expected majority in the Assembly?; and (ii) what broader lessons does this case-study offer for the study of elections in the UK under devolution? Drawing on data from the Welsh National Assembly Election Study, we find that while some features of second-order election theories, such as lower turnout and a lower vote share for the governing party were manifest, contrary to the predictions of such theories the surge in electoral support for Plaid was largely prompted by Welsh-specific factors rather than UK-wide ones. The findings are argued to indicate limits to the applicability of second-order approaches to the study of devolved elections in the UK.
