Much discussion of electoral integrity focuses on new democracies. This paper seeks to identify determinants of electoral integrity in an established democracy: Britain. A novel measure of electoral integrity is brought together with comprehensive multi-level data on: the costs of electoral administration; whether concurrent elections were being held; size of electorate; number of constituencies administered; region; type of administration overseeing local electoral administration; and the number of staff employed on administering the electoral process. The results will establish a range of relationships to electoral integrity which will inform subsequent debates on election quality in other democracies, whether advanced or otherwise.
