Taking stock: what have we learned from the European elections?

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

The European Parliament elections: seven things you need to know

Nominations for election to the European Parliament closed on Thursday. We now know which parties will be contesting the elections (if they happen), and who those parties have selected to stand for them in each region of the UK. The Unit’s Alan Renwick offers a brief guide to how the elections will work and what we can expect to learn from them.

With little sign of progress in the Brexit talks between the government and the Labour Party, UK participation in next month’s European Parliament elections looks increasingly likely. The parties have nominated their candidates and begun to launch their campaigns. Much is being said about how the electoral system will shape the outcome, but not all of it is accurate. This post provides a quick guide to the key points and reaches two main conclusions. First, the system will disadvantage small parties: in particular, the anti-Brexit parties will be punished for their disunity. Second, anyone wanting to read the results as a proxy second Brexit referendum will need to do so with great care.

1. The system is proportional…

The UK uses a system of proportional representation (PR) for European Parliament elections. To be precise, it uses two different systems. England, Scotland, and Wales use a list-based form of PR, which was introduced to replace the old First Past the Post system in 1999. This is based on 11 regions, each electing between three and ten MEPs. Each party puts up a list of candidates and voters choose one party’s list. The seats are allocated to the parties in each region in proportion to the votes that they have won.

Northern Ireland, by contrast, has used the Single Transferable Vote (STV) form of PR ever since the first elections to the European Parliament in 1979. Each party again puts up a slate of candidates. But voters rank individual candidates in order of preference, and these votes are counted and transferred according to the preferences expressed until the three seats available have been filled.

Proportional systems make it easier than under First Past the Post for small parties to secure seats. Last time around, for example, the Green Party won three seats with 7.87% of the vote, whereas in 1989, under First Past the Post, it famously captured 14.5% of the vote but no seats at all.

2. …but not all that proportional

‘Proportional’ systems vary in just how proportional they are. In fact, neither of the systems used in the UK is especially so, for two reasons. First, the number of seats available in each region constrains how far it is possible to allocate seats proportionally. In the North East of England, for example, where there are only three seats, it is clearly impossible for any more than three parties to win representation. Even the largest region – the South East, with ten seats – is quite small in seat terms, making it impossible to reflect the pattern of votes perfectly in the allocation of seats. Continue reading
