The electoral system of Turkey varies for general, presidential and local elections that take place in Turkey every five years. Turkey has been a multi-party democracy since 1950 (officially since 1945), with the first democratic election held on 14 May 1950 leading to the end of the single-party rule established in 1923. The current electoral system for electing Members of Parliament to the Grand National Assembly has a 7% election threshold.
A brief summary of the electoral systems used for each type of election is as follows:
General elections: The D'Hondt method, a party-list proportional representation system, to elect 600 Members of Parliament to the Grand National Assembly from 87 electoral districts that elect different numbers of MPs depending on their populations. Local elections: Metropolitan and District Mayors, Municipal and Provincial Councillors, neighbourhood presidents and their village councils elected through a first-past-the-post system, with the winning candidate in each municipality elected by a plurality. Presidential elections: A two-round system, with the top two candidates contesting a run-off election two weeks after the initial election should no candidate win at least 50%+1 of the popular vote.
General elections
Turkey elects 600 Members of Parliament to the Grand National Assembly using the D'Hondt method, a party-list proportional representation system. In order to return MPs to parliament, a party needs to gain more than 7% of the vote nationwide by itself or by being a member of an electoral alliance whose aggregate votes passes the said threshold. This means that parties may win the most votes in certain areas but not win any MPs due to a low result overall. The parliamentary threshold, which stayed as high as 10% between 1982 and 2022, has been subject to intense scrutiny by opposition members, since all votes cast for parties polling under 10% are spoilt and allow the parties overcoming the national threshold to win more seats than correspond to their share of votes. E.g. in the 2002 general election the AK Party won 34.28% of the vote but won nearly two-thirds of the seats.
The parliamentary threshold does not apply to independents, meaning that Kurdish nationalist politicians who poll strongly in the south-east but are not able to win 10% of the overall vote stand as independents rather than as a party candidate. This was the case in the 2007 and 2011 general election, where the Kurdish Democratic Society Party and the Peace and Democracy Party fielded independent candidates respectively.
Ahead of the 2018 general election, Electoral System was altered to accommodate for election alliances, allowing parties to enter elections as coalitions of multiple parties, where as long as the aggregate votes of the alliance passes the electoral threshold the threshold is ignored for the parties within the coalition, effectively opening a way for parties to bypass the electoral threshold. Effects of the change was first observed in the same elections, where Good Party, despite its 9.96% votes laying below the then 10% threshold, was able to enter the parliament due to being part of the larger Nation Alliance, whose total vote was 33.95%.
While initially the D'Hondt method was applied proportionally to all alliance members, a bill overseeing alterations to the election law passed on 31 March 2022 changed the system so that each party that passes the new 7% threshold either by itself or by being a member of an electoral alliance are directly represented by its own votes in each constituency when the calculations of D'Hondt are being made, disallowing smaller members of an electoral alliance from gaining MPs in the strongholds of their larger allies' strongholds due to their overall percentage contribution to the alliance.
Proposals for reform The main criticism of the current system has long been the unusually high 10% threshold necessary to gain seats. In January 2015, the CHP renewed their parliamentary proposals to lower the threshold to 3% and proposed no changes to the proportional representation system, though the AK Party has been against lowering the threshold without wider electoral reform.
In July 2013, the AK Party prepared new proposals, named the 'narrow district system' (daraltılmış bölge sistemi), to change the proportional representation system into either a first-past-the-post system or create smaller constituencies which elect a fewer number of MPs. Under these proposals, the threshold would fall from 10% to either 7 or 8% while Turkey would be split into 129 electoral districts rather than the existing 85. Istanbul itself would have been split into 17 or 20 districts. The system will benefit the largest party as well as parties that are the strongest in certain regions, meaning that the AK Party and Kurdish nationalist Peace and Democracy Party (BDP) would make the biggest gains. The two main opposition parties CHP and MHP do not have a substantial number of electoral strongholds, meaning that they would be negatively impacted by a narrow-district system. Proposals by the AK Party to create a full first-past-the-post system with 550 single-member constituencies were allegedly unveiled in December 2014, though any change in electoral law would have to be passed by parliament at least a year before the election. The AKP's proposals for reform have raised concerns about gerrymandering.
Criticisms regarding the high threshold were largely relieved upon the electoral alliance system was adopted, allowing smaller parties to pass the threshold as a member of a larger alliance. Nevertheless, the current 7% threshold is still considerably high, blocking the path of small parties such as Patriotic Party that cannot make their way into a larger alliance. Moreover, the need for a threshold remains to be questionable ever since the presidential elections were split from parliamentary elections since 2018.
Electoral districts Turkey is split into 87 electoral districts, which elect a certain number of Members to the Grand National Assembly of Turkey. The Grand National Assembly has a total of 600 seats (increased from 550 seats after 2017 constitutional reforms) a, which each electoral district allocated a certain number of MPs in proportion to their population. The Supreme Electoral Council of Turkey conducts population reviews of each district before the election and can increase or decrease a district's number of seats according to their electorate.
