Apportionment in the European Parliament

The apportionment of seats within the European Parliament to each member state of the European Union is set out by the EU treaties. According to European Union treaties, the distribution of seats is "degressively proportional" to the population of the member states, with negotiations and agreements between member states playing a role.[1] Thus the allocation of seats is not strictly proportional to the size of a state's population, nor does it reflect any other automatically triggered or fixed mathematical formula. The process can be compared to the composition of the electoral college used to elect the President of the United States of America in that, pro rata, the smaller state received more places in the electoral college than the more populous states.

After the withdrawal of the United Kingdom from the EU in 2020, the number of MEPs, including the president, dropped to 705[2] but since the 2024 election, it increased to 720.[3] The maximum number allowed by the Lisbon Treaty is 751.

Background

edit

When the Parliament was established in 1952 as the 78-member "Common Assembly of the European Coal and Steel Community" the then-three smaller states (Belgium, Luxembourg, and the Netherlands) were concerned about being under-represented and hence they were granted more seats than their population would have allowed. Membership increased to 142 with the Assembly expanded to cover the Economic and Atomic Energy Communities.[4] It then grew further with each enlargement, which each time allowing smaller nations to have greater proportion of seats relative to larger states.

Relative influence of voters from different EU member states (2024 - 2029)[5]

Influence is proportional to seats-to-votes ratio and inversely proportional to Inhabitants to MEPs ratio.

Nice system (2003 – 2009)

edit
 
Number of seats plotted against the population of each State (Nice 2007)

The Nice Treaty provided for a maximum of 736 seats. In 2009, with about 500 million EU citizens, this meant that there were on average 670,000 citizens represented by each MEP. Some states divide the electorate for their allocated MEPs into sub-national constituencies. However, they may not be divided in such a way that the system would no longer be proportional.

The 2004 European Parliament election was the first conducted under the Nice Treaty, with 732 seats for the 25 member states.

The 2009 European Parliament election was conducted under the rules included in the Nice Treaty which provided for a maximum number of 736, although that figure had been breached on the accession of new members to the EU, these states being allowed parliamentary representation without a corresponding reduction in the number of MEPs allotted to other member states. This happened in 2007 on the accession of Romania and Bulgaria, when the number of seats temporarily increased to 785. It subsequently returned to 736 in the 2009 election.[4]

Lisbon system (2009 – present)

edit

Under the Lisbon Treaty, which first applied to the 2014 European Parliament election, the cap on the number of seats was raised to 750, with a maximum of 96 and a minimum of 6 seats per state. They continue to be distributed "degressively proportional" to the populations of the EU's member states.[7]

  3. ^ a b The speaker is not counted officially, thus leaving 750 MEPs.

There was controversy over the fact that the population figures are based on residents, not citizens, resulting in countries with larger disenfranchised immigrant populations gaining more under Lisbon than those with smaller ones.[9] Italy would have been the greatest loser under the Lisbon system and sought the same number of MEPs as France and the United Kingdom. Italy raised the issue during treaty negotiations and succeeded in gaining one extra MEP (giving it the same as the UK) while the President of the European Parliament would not be counted as a lawmaker hence keeping the number of MEPs to the 750-seat limit.[10]

2011 amendment

edit

In 2011 an amendment, which came into force on 1 December, temporarily increased the Lisbon limit to 754.[11][12][13][14] This allowed member states who gained seats under Lisbon to take them before the 2014 election, while allowing Germany which lost seats under Lisbon to retain them until the 2014 election. This amendment, in effect, institutes a transitional manner of distributing MEPs to take account of the fact that the 2009 European Parliamentary elections took place under the rules contained in the Nice Treaty and not in the Lisbon Treaty. That result means that member state that are to gain seats in parliament under the Lisbon rules may take them, but that Germany which loses three seats under the Lisbon rules keeps those seats until the next elections, due in 2014.[15] As a result, Germany temporarily exceeds the maximum number of MEPs allocatable to a member state under the Lisbon Treaty by having 99 MEPs, three above the intended limit.

2013 amendment

edit

Following the accession of Croatia on 1 July 2013 with 12 extra seats, the apportionment was amended for the 2014 elections,[8] when 12 countries lost one seat (including Croatia itself).

2014 election

From October 2008,[16] MEP Andrew Duff (ALDE, UK) has advocated within the European Parliament for a reform of EU electoral law for the 2014 elections, including the creation of a single constituency of 25 seats in which each European citizen would be entitled to vote on the basis of pan-European lists. He has been nominated rapporteur, as the European Parliament has the right of initiative in this field ruled by unanimity in the Council. After the 2009 election, Duff proposed a new version of his report,[17] which was adopted by the parliamentary Committee on Constitutional Affairs (AFCO) in April 2011. However, the plenary session of the Parliament referred the report back to the AFCO committee in July 2011. A third version of the report[18] was published in September 2011 and adopted by the AFCO committee in January 2012, but was withdrawn before being discussed in plenary in March 2012 for fear that it would likely be turned down.

On 13 March 2013 the European Parliament voted a new proposal updating seat assignments per country for 2014,[8] taking into account demographic changes and bringing the total number of seats back to the nominal 751 enshrined in the Lisbon Treaty. The same document suggests the creation of a formal process "based on objective criteria to be applied in a pragmatic manner" for apportioning seats in future elections.

2019 election

edit

The EU needed to revise the apportionment of seats in time for the next European Parliament election, expected to be held in May 2019, when the United Kingdom's 73 MEPs may have vacated their seats following Brexit. In April 2017, a group of European lawmakers discussed what should be done about the vacated seats. One plan, supported by Enrico Letta, Gianni Pittella and Emmanuel Macron, was to replace the 73 seats with a pan-European constituency list. Other options which were considered include dropping the British seats without replacement and reassigning some or all of the existing seats from other countries to reduce inequality of representation.[26] A plan to reduce the number of seats to 705 was approved by the Parliament in February 2018. It involves redistributing 27 seats to under-represented members and reserving the remaining 46 for future EU expansions. A proposal by the Constitutional Affairs Committee to create a pan-member constituency was rejected by the Parliament at the same time.[27] The proposed redistribution did not occur due to the Brexit extension until 31 October, and the allocation used was the same as in 2014. After Brexit took legal effect, the seat distribution was decided by the European Council. Those countries which were allocated additional seats elected MEPs who only took office after Brexit had taken effect.

2024 election

edit

In February 2023, the AFCO committee of the European Parliament released a draft report (whose rapporteurs are Lóránt Vincze and Sandro Gozi) on the necessary changes to the composition of the European Parliament in order to respect the principle of degressive proportionality (enshrined in the TEU). The draft report suggested a new apportionnement which aimed at respecting the degressive proportionality while also resulting in no loss of seats for any Member State, therefore leading to an expansion in the number of MEPs, from 705 to 716.[33] On 12 June 2023, the report was approved by the AFCO committee, with the apportionment being unchanged compared to the draft report.[34] On 15 June 2023 the report was approved by the EP plenary.[35]

In July 2023, the European Council put forward its own proposed apportionment for the tenth European Parliament, which would add 15 new MEPs and thus take the number of seats from 705 to 720.[36] In this proposal, no Member State would lose any spots in the hemicycle and the countries gaining new seats would be as indicated in the table below under New allocation of seats (final decision for 2024).

On 15 September 2023, the European Parliament approved the apportionment proposed by the Council, with 515 votes in favor, 74 against and 44 abstentions.[3]

Furthermore, this decision envisages the future (before the 2029-2034 parliamentary term) definition of "an objective, fair, durable and transparent seat distribution method implementing the principle of degressive proportionality, without prejudice to the institutions’ prerogatives under the Treaties".
