Inside the ‘secret garden’: Candidate selection at the 2019 UK general election

Candidate selections are seen as the ‘secret garden’ of UK politics. Hundreds of parliamentary constituencies rarely change hands, meaning that the ‘real election’ is the incumbent party’s selection process. Yet scholarship into candidate selection in the United Kingdom remains limited. In this article, we build a novel dataset of known shortlisted candidates in winnable seats to offer the first cross-party analysis of who gets shortlisted, and what factors influence success among shortlisted candidates. We find that shortlisted female and ethnic minority candidates are still less likely to be selected as parliamentary candidates, while living locally is by far the most significant factor affecting selection success. However, the nature of the 2019 snap election allowed parties to use emergency powers to advantage party insiders in late selections. We further find that, contrary to media focus, party faction was not a significant factor in Conservative or Labour Party selections.
