Last week, voters across the UK (and indeed, across the European Union) took part in the European Parliament elections. Now that we know the outcome, Alan Renwick examines the impact on the results of both the rules that governed the election and the strategies of the parties.
The European elections raised important questions about how the voting system – and parties’ and voters’ reactions to it – might influence the results. Would the imperfect proportionality of the system harm the smaller parties? Should those parties – particularly the three Britain-wide anti-Brexit parties – have formed an alliance? Could voters maximise the impact of their ballots through tactical voting? Now that the results are in, it is time to take stock.
The impact of the rules
As I set out in an earlier post, European Parliament elections in Great Britain use a list-based system of proportional representation (while those in Northern Ireland use Single Transferable vote, or STV). This system is proportional, but not very. The D’Hondt formula for allocating seats favours larger parties. So does the fact that the number of seats available in each region (ranging from three in the North East of England to ten in the South East) is fairly low.
The results would certainly have been different had the elections been held using First Past the Post, as was the case for European elections in Great Britain before 1999. This system, still used for Westminster elections, awards a seat to the largest party in each constituency. Had voters cast the same votes as they did on Thursday, the Brexit Party would under First Past the Post have won almost every seat in England and Wales outside London and the Home Counties; the Liberal Democrats and Labour would have dominated in London and parts of its environs; the SNP would have captured every seat in Scotland; and the Conservatives would have been wiped out. In fact, many voters would not have cast the same votes as they did. For example, the anti-Brexit parties could probably have agreed joint candidates much more easily than under the actual system, helping them to secure some extra seats. But the Brexit Party would very likely still have scooped up most seats on less than a third of the vote. Continue reading
