By‐Elections and Political Change in a Local Context: The Case of the 1973 Dundee East By‐Election and the SNP

With their unpredictability and occurrence in between nationwide elections, by‐elections have attracted a degree of scholarly interest. However, this has focused almost exclusively on how the contests have affected, or failed to affect, the direction of national politics. This article seeks to, instead, explore their influence upon the locality in which they are fought. It will achieve this through an analysis of the 1973 Dundee East by‐election and its consequences for the development of the local Scottish National Party (SNP). Prior to the by‐election, the party had not been particularly strong in Dundee. Yet the contest provided a setting in which it was able to transform itself into one of the most effective Nationalist organisations in Scotland, capable of cementing an SNP MP in the constituency from 1974 until 1987, holding firm against the collapse in the party's support across the country in the late 1970s and early 1980s. The article will examine the extent to which this resistance to the national swing was facilitated by the legacies of the by‐election and the extent to which its wider footprint contributed towards the development of an enduring party tradition that has persisted for decades.
