Seats allocation Parliamentary seats are allocated according to the d’Hondt method in a party-list proportional representation system. Political parties first need to pass an electoral threshold of 7%. Parties can by-pass this rule by forming an electoral alliance or participate as independents. The electoral threshold was introduced by the military regime after the 1980 coup d'état, in a bid to maintain political stability.

From 1946 onwards, all elections were direct elections. In the elections held between 1946 and 1957, a party block voting system was applied. Under this system, the party that obtained a plurality of votes in a constituency would get all the deputies in that constituency. The system resulted in a landslide victories. For example, the Democrat Party received 58% of the votes in the 1954 election, but won 93% of the seats in the parliament.

Proportional representation was used for the first time after the adoption of the Constitution of 1961. For the elections of 1961, a party-list proportional representation with the D'Hondt method in 67 constituencies was used. In order to receive seats in a constituency, parties needed to receive more votes in that constituency that the Hare quota. It was also the first time that the number of deputies was fixed and determined as 450 seats.

In the 1965 election, the national remnant system was used. In the elections held in 1969, 1973 and 1977, the d'Hondt electoral system was applied without a threshold. A nationwide electoral threshold of 10% and a constituency electoral threshold was introduced following the changes to the law in 1983. In addition to that, a quota system was also used in the 1987 and 1991 elections. From 1995 onwards, only a nationwide electoral threshold is used.

Campaigning The Law on Basic Provisions regulates the campaign and aims to ensure fair and equitable opportunities for contestants. Turkish campaigns are typically energetic as contestants use a variety of traditional campaigning means such as rallies, campaign stands, posters, banners, party flags, canvassing and vehicles with loudspeakers. Languages other than Turkish as well as sign language are used in the campaigns. According to Turkish Law, it is forbidden to make election propaganda in a foreign country. This law can be circumvented to a certain degree by organizing "informative seminars" instead of "propaganda meetings".

Political parties that received at least three per cent of votes in the last parliamentary elections are entitled to annual public funding on a proportional basis, as well as campaign funding but only for parliamentary elections. Parties also receive funding through membership fees and individual donations. Donations from public legal entities, state and public organizations and foreign sources are not allowed. An individual may donate up to a certain amount annually to a party. There is no ceiling for annual party and campaign-related expenditure. Parties declare their campaign funds solely through annual financial reports. The Constitutional Court audits the reports. Independent candidates declare their campaign funds through personal tax declarations. Possible sanctions for breaches include warnings, imprisonment from three months to three years, monetary fines and dissolution of the party.
