resul_umitAs Theresa May selects the members of her new government, there is more and more speculation about who the new ministers will be. Here, Resul Umit writes that although previous experience and policy preferences matter, electoral majorities also do: MPs holding safe seats are more likely to be selected for ministerial office.

Existing research on government selection provides evidence for the importance of previous experience and policy preferences. However, they are missing a key factor in legislative behaviour: electoral safety. In a recent study with Elad Klein, we show that members of parliament (MPs) in electorally safe seats are more likely to become ministers in the United Kingdom (UK).

This is based on an analysis whether the constituency results from the elections to the House of Commons over the period 1992–2015 influenced the likelihood of MPs being selected as ministers in the UK. The House of Commons provides the perfect case to assess the electoral connection of ministerial selection due to the single-member districts, large government size, and the relatively decentralised candidate selection process in the UK.

Electoral safety affects the ministerial selection because elections are a constraint over the preferences of MPs and their parties. MPs need to stay in the parliament by being re-elected to be able to pursue other goals, including attaining promotion to government ranks. On the other hand, party leaders need to maximise the number of their MPs in order to stay in the government to achieve their policy ideals.

Electoral constraints differ with the marginality of seats for each MP in Westminster systems. In single-member districts, it is comparatively clear to members and to their leaders how electorally safe their parliamentary seats are. As the electoral marginality of a seat increases, or in other words as the number of votes separating success from failure to secure a seat decreases, re-election becomes the dominant motivation.

Our results show that there is indeed a positive relationship between MPs electoral safety and their probability of securing a ministerial office. The figure below plots the predicted probabilities of government post allocation across the different degrees of electoral safety, where dotted lines indicate the 95 per cent confidence interval around the fitted line. For an MP with 5 per cent electoral safety, which is often considered as marginal, the probability of becoming a minister is one in 10. In contrast, a 35 per cent majority more than doubles this probability for MPs.

There are at least two important implications of this result. First, if electoral safety increases MPs’ chances of becoming ministers, electorates can affect not only who selects the ministers but also who get selected as ministers. Voters elect their members of parliament in general elections, but a large majority of MPs have very little to do with the day-to-day governing of the country. It is rather the ministers in government, as selected by party leaders, who do. Second, if MPs and party leaders prioritise electoral safety before ministerial office, the results also mean that there is an empirical evidence for the hierarchy of legislative goals—an important theoretical assumption in rational approaches to legislative behaviour.

Electoral safety is particularly important for junior MPs to become ministers. Once they spend long enough in parliament, which roughly 20 years according to our results, electoral safety does not significantly affect their chances of entering the government anymore. Senior MPs enjoy the reputation that they have built in time among their constituents, and those who have done so can then spend more resources on other goals, such as attaining a ministerial office, and less on the goal of re-election. Think about for example a senior MP with 30 years’ experience in the parliament. She is less likely to be alarmed about a 5% electoral majority than a newly elected MP. The former is less likely to feel unsafe with the same amount of a cushion of votes, and therefore more likely to go for a ministerial position with all the experience that comes with seniority.

A risk of linking election results to ministerial selection is that the causality might run in either direction, depending on the candidate selection processes in political parties. If party leaders in the UK “parachuted” their would-be ministers to safe seats before general elections, it would not be meaningful to talk about any effect of electoral safety on ministerial selection. However, the effect of electoral safety continues to hold among those MPs who lost an election before entering the parliament. It is reasonable to assume that such MPs, who had unsuccessful attempts at being elected, were not centrally posted to these constituencies become ministers later on.

One of the other controls in the study relates to gender. On the one hand, as evident in the increasing but still unfair share of female MPs in the House of Commons, female citizens are less likely to become parliamentary representatives. Those females who make it to the parliament, on the other hand, are more likely to become ministers according to the results. This confirms the commitment of political parties in the UK to increase women’s representation in government.
