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
