Elections to the European Parliament take place every five years by universal adult suffrage. 751 MEPs are elected to the European Parliament, which has been directly elected since 1979. No other EU institution is directly elected, with the Council of the European Union and the European Council being only indirectly legitimated through national elections. While Europarties have the right to campaign EU-wide for the European elections, campaigns still take place through national election campaigns, advertising national delegates from national parties.
The allocation of seats to each member state is based on the principle of degressive proportionality, so that, while the size of the population of each country is taken into account, smaller states elect more MEPs than is proportional to their populations. As the numbers of MEPs to be elected by each country have arisen from treaty negotiations, there is no precise formula for the apportionment of seats among member states. No change in this configuration can occur without the unanimous consent of all governments.
There is no uniform voting system for the election of MEPs; rather, each member state is free to choose its own system, subject to certain restrictions:
Country by country
Most of the member states of the European Union elect their MEPs with a single constituency covering the entire state, using party-list proportional representation. There is however a great variety of electoral procedures: some countries use the highest averages method of proportional representation, some use the largest remainder method, some open lists and others closed. In addition, the method of calculating the quota and the election threshold vary from country to country. Countries with multiple constituencies are:
Germany, Italy and Poland use a different system, whereby parties are awarded seats based on their nationwide vote as in all of the states that elect members from a single constituency; these seats are given to the candidates on regional lists. With the number of seats for each party known, these are given to the candidates on the regional lists based on the number of votes from each region towards the party's nationwide total, awarded proportionally to the regions. These subdivisions are not strictly constituencies, as they do not decide how many seats each party is awarded, but are districts that the members represent once elected. The number of members for each region is decided dynamically after the election, and depends on voter turnout in each region. A region with high turnout will result in more votes for the parties there, which will result in a greater number of MEPs elected for that region.
The European Union has a multi-party system involving a number of ideologically diverse Europarties. As no one Europarty has ever gained power alone, their affiliated parliamentary groups must work with each other to pass legislation. Since no pan-European government is formed as a result of the European elections, long-term coalitions have never occurred.
Europarties have the exclusive right to campaign for the European elections; their parliamentary groups are strictly forbidden to campaign and to spend funds on any campaign-related activity. For the 2014 EP election, Europarties decided to put forward a candidate for President of the European Commission; each candidate will lead the pan-European campaign of the Europarty. While no legal obligation exists to force the European Council to propose the candidate of the strongest party to the EP, it is assumed that the Council will have no other choice than to accept the voters decision.
The two major parties are the centre-right European People's Party and the centre-left Party of European Socialists. They form the two largest groups, (called EPP and S&D respectively) along with other smaller parties. There are numerous other groups, including communists, greens, regionalists, conservatives, liberals and eurosceptics. Together they form the seven recognised groups in the parliament. MEPs that are not members of groups are known as non-inscrits.
A 1980 analysis by Karlheinz Reif and Hermann Schmitt concluded that European elections were fought on national issues and used by voters to punish their governments mid-term, making European Parliament elections de facto national elections of second rank. Turnout has been falling steadily since the first elections in 1979, indicating increased apathy about the Parliament despite its increase in power over that period. Turnout has constantly fallen in every EU election since 1979. In 2009, the overall turnout was at 43%, down from 45.5% in 2004. In Britain the turnout was just 34.3%, down from 38% in 2004. Despite falling below 50% since 1999, turnout is not yet as low as that of the US Midterm elections, which usually falls below 40%. However, the comparison with the US voter turnout is hampered due to the fact that the US President is elected in separate and direct elections (presidential system), whereas the President of the European Commission is only approved by the European Parliament (parliamentary system), giving the European Parliament elections considerable weight. Some, such as former President of the European Parliament, Pat Cox, have also noted that turnout in the 1999 election was higher than the previous US presidential election. German MEP Jo Leinen has suggested that EU parties name their top candidate for the position of President of the European Commission in order to increase turnout.

Legend: Socialist (PES/S&D) – Liberal (ELDR/ALDE) – People's (EPP/EPP-ED)
As of 2011 reforms by Liberal Democrat MEP Andrew Duff are being considered by Parliament, which are seen as the most significant overhaul of the electoral system since elections began. 25 extra MEPs would be added on a transnational European list with its candidates being selected by the European party groups rather than national member parties. The candidate lists would have to represent a third of member states and are seen as a way to personalise and dramatise the elections to re-engage an apathetic electorate. Duff sees the next Commission President possibly coming from the transnational list. Duff's proposals also include a single electoral roll, regular reapportioning of seats, one set of immunity rules and the holding of elections in May rather than June. However, due to a waning of support and possible opposition from member states, Duff has taken the proposal back to committee to get broader support before putting them before the plenary in autumn 2011.
The third Delors Commission had a short mandate, to bring the terms of the Commission in line with that of the Parliament. Under the European Constitution the European Council would have to take into account the results of the latest European elections and, furthermore, the Parliament would ceremonially "elect", rather than simply approve, the Council's proposed candidate. This was taken as the parliament's cue to have its parties run with candidates for the President of the European Commission with the candidate of the winning party being proposed by the Council.
This was partly put into practice in 2004 when the European Council selected a candidate from the political party that won that year's election. However at that time only one party had run with a specific candidate: the European Green Party, who had the first true pan-European political party with a common campaign, put forward Daniel Cohn-Bendit. However the fractious nature of the other political parties led to no other candidates, the People's Party only mentioned four or five people they'd like to be President. The Constitution failed ratification but these amendments have been carried over to the Treaty of Lisbon, which came into force in 2009.
There are plans to strengthen the European political parties in order for them to propose candidates for the 2009 election. The European Liberal Democrat and Reform Party have already indicated, in their October 2007 congress, their intention for forward a candidate for the post as part of a common campaign. They failed to do so however the European People's Party did select Barroso as their candidate and, as the largest party, Barroso's turn was renewed. The Socialists, disappointed at the 2009 election, agreed to put forward a candidate for Commission President at all subsequent elections. There is a campaign within that party to have open primaries for said candidate.
In February 2008, President Barroso admitted there was a problem in legitimacy and that, despite having the same legitimacy as Prime Ministers in theory, in practice it was not the case. The low turnout creates a problem for the President's legitimacy, with the lack of a "European political sphere", but analysis claim that if citizens were voting for a list of candidates for the post of president, turn out would be much higher than that seen in recent years.
With the Lisbon Treaty now in-force, Europarties are obliged from now-on to put forward a candidate for President of the European Commission; each Presidential candidate will, in fact, lead the pan-European campaign of the Europarty.
The President of the European Parliament Jerzy Buzek proposed in 2010 that Commissioners be directly elected, by member states placing their candidate at the top of their voting lists in European elections. That would give them individually, and the body as a whole, a democratic mandate.
Each Member State has different rules determining who can vote for and run as the European Parliamentary candidates.
Every EU citizen residing in an EU country of which he/she is not a national has the right to vote and to stand as a candidate in European Parliamentary elections in his/her country of residence, under the same conditions as nationals of that country - this right is enshrined in Article 39 of the Charter of Fundamental Rights of the European Union. In addition, the right to vote is included in Articles 20(1) and 22(1) of the Treaty on the Functioning of the European Union. To this extent all EU countries keep electoral registers containing the names of all eligible voters in the specific region, to which eligible newcomers to the area can apply at any time to have their names added. EU citizens are then eligible to vote for the duration of their stay in that country.
It is therefore possible for a person to have the choice of voting in more than one EU member state. For example, a Portuguese citizen who studies at university in France and lives at home outside term-time in the family home in the United Kingdom has the option of voting in the European Parliamentary election in France, Portugal or the United Kingdom. In this scenario, although the Portuguese citizen qualifies to vote in three EU member states, he/she is only permitted to cast one vote in one of the member states.
Currently, no pollster is doing any Europe-wide electoral polling. However, some websites give projections for the result of the next European Parliament election based on national polls for each EU member state. These results are usually indicated in seats.
In the following table, the values of the ENF member parties before the constitution of the group in June 2015 are indicated in brackets.
The magazine of the Young European Federalists also publishes prognoses indicating the percentage of the seats of each parliamentary group. However, these prognoses are also based on national (rather than Europe-wide) polls. As the European election system is not directly proportional on the pan-European level, the seat percentages do not necessarily correspond to the number of voters of each parliamentary group.
