Of the 16 parties registered to contest today's election in Turkey the polls suggest the same four will pass the 10 percent electoral threshold.
The Justice and Development Party
Led by Prime Minister Ahmet Davutoglu, the Justice and Development (AK) Party is looking to regain its majority in parliament and increase the number of its seats from 258.
The party won more than 49 percent of the vote in the 2011 general election and its candidate won 52 percent in the presidential election last August but this fell to less than 41 percent in June.
The party, which has based much of its popularity on its economic record and an appeal to traditional Muslim values, counts central Anatolia as its stronghold, as well as key provinces such as Istanbul and Ankara.
Republican People’s Party
Turkey's left-wing main opposition party, the Republican People's Party (CHP), established by Turkey’s founder Mustafa Kemal Ataturk is looking for a significant boost from June’s result, which saw it take nearly 25 percent of the vote and win 132 seats. One of its deputies has since become an independent.
Its campaign has focused on reforming the economy, education, the judiciary and politics. The party’s strongholds include the coastal provinces of Izmir and Antalya.
Nationalist Movement Party (MHP)
Headed by Devlet Bahceli, the nationalists, like other the AK Party and CHP, have pledged to secure better conditions for public sector workers and pensioners.
The MHP has also said it would reverse the “solution process” initiated by the AK Party to end the Kurdish conflict and take a tough stance on terrorism and defeat the PKK.
The party receives the bulk of its support from central Anatolia, where it has usually comes second to the AK Party in conservative provinces. The party secured just over 16 percent of the vote in June, taking 80 seats. It has also lost a single deputy since the last election.
Peoples' Democratic Party
The Peoples' Democratic Party (HDP) which has added to its traditional Kurdish base an appeal to left-wing progressives, gained 80 seats in June’s poll and took more than 13 percent of the vote nationwide.
Led by Selahattin Demirtas and Figen Yuksekdag, the party has been heavily involved in the solution process to resolve Turkey’s three-decade long Kurdish conflict as a bridge to the PKK.
The party is strongest in Turkey’s eastern and southeastern provinces and hopes to win leftist votes in the provinces.
Other parties standing on Sunday are the Independent Turkey Party; the Grand Unity Party; the Democratic Party; the Democratic Left Party; the Communist Party; the Nation Party; the Felicity Party; the Patriotic Party; the People's Liberation Party; the Rights and Liberties Party; the True Path Party; and the Liberal Democratic Party.
