The Impact of Brexit on Voting Behaviours in the UK

Introduction

Brexit has played a significant role in the reshaping of normal patterns of voting behaviour in the UK in the years since the 2016 referendum.  (Webb and Bale 2021) In the aftermath of the referendum, the UK electorate seems to have moved beyond traditional divisions which influenced voting behaviour in British politics. For years, voting behaviour appeared to display that Labour could count on working class support whilst the Conservatives could rely on middle class support. However, voting behaviour in recent years displays that these rules no longer seem to apply. (Surridge 2021)

Realignment trends in voting behaviour:

Realignment describes major shifts in the traditional basis of party support based on structural cleavages. Realignment is a process of transition in electoral systems where new cleavages are formed, cross-cutting traditional cleavages and influencing patterns of electoral support. (Webb and Bale 2021)

Historically in Britain, the main cleavage to define voting behaviour was class divisions with the lower class traditionally voting Labour, and the middle class traditionally voting Conservative. (Surridge 2021). However, in the general elections held post-Brexit referendum, it appears that the opposite trend has emerged. Graduates, who are more likely to be in middle class jobs were more likely to vote Remain and as a result were more likely to vote Labour. In contrast, Labour’s traditional working class voter base were more likely to support Leave, and so moved towards the Conservatives. (Curtice 2023)

After the 2016 referendum, the Conservatives new stance on pursuing a “Hard Brexit”, appeared to make them the party most likely to get Brexit done, resulting in their support from Leave voters increasing from 44-75% between 2015 and 2019. (Fieldhouse et al 2023). The issue of Brexit was prominent in the realignment of working-class voters, 62% of whom voted Leave, driving them to defect to the Conservatives in the 2017 and 2019 General Elections (Webb and Bale 2021).

(Fieldhouse et al 2023)

The loss of traditional Labour voters to the Conservatives is symbolised in the changing geographic basis of support in the 2019 general election with the collapse of Labour’s “red wall” in the North of England, where constituencies held by Labour for decades were lost to the Conservatives, strongly indicating a Brexit realignment in UK voting behaviours. (Fieldhouse et al 2023).

(BBC News 2019)

Brexit has also created new levels of polarization among British voters, resulting in the production of a new values divide. (Hobolt et al 2020). In the aftermath of the realignment caused by Brexit, competing social political identities have come to fill the gap created by the decline in traditional party identification. As many voters are likely to identify as members of the ‘Leave’ or ‘Remain’ groups as they are with any particular political party. (Webb and Bale 2021). In 2017 and 2019, both Remain and Leave identities were stronger on average than traditional party identification measured on the same scale. (Fieldhouse et al. 2020).

Issues associated with Brexit and EU membership connects voters’ opinions with a wider set of values and attitudes towards immigration, identity, social liberty and authority, explaining why Brexit preferences have a high potential to create a lasting realignment in voting behaviour in the UK. (Webb and Bale 2021)

Conclusion:

Whether Brexit caused a lasting realignment in voting behaviour in the UK, will become clearer after the next UK general election, which is due to be held before 28th January 2025, with PM Rishi Sunak announcing intentions that it will be held in the latter half of this year. (Edgington 2024)

It is highly unlikely that the issue of Brexit will dominate in the upcoming election campaigns in the same way as it did in the past two general elections, yet evidence shows that how people voted in the 2016 referendum still helps to predict their voting behaviour today. (Curtice 2023)

Whilst the link between Brexit preference and voting behaviour may be weaker now than in the last general election four years ago, it has not disappeared from Britain’s electoral landscape. (Curtice 2023) Whether Brexit played a long-lasting role in changing voting behaviours in the UK remains to be seen, but we can be certain that class is no longer the main cleavage to influence voting behavior in the UK.
