Early elections to be held in Turkey
There are a total of six presidential candidates -- Muharrem Ince, Meral Aksener, Recep Tayyip Erdogan, Selahattin Demirtas, Temel Karamollaoglu and Dogu Perincek.
Eleven political parties are contesting the early elections: ruling Justice and Development (AK) Party, Grand Unity Party (BBP), Independent Turkey Party (BTP), main opposition Republican People's Party (CHP), Democrat Party (DP), Peoples' Democratic Party (HDP), Free Cause (Huda-Par) Party, newly-formed Good (IYI) Party, Nationalist Movement Party (MHP), Felicity (Saadet) Party and the Patriotic (Vatan) Party.
Last April, the parliament passed a bill for early elections on June 24, cementing Turkey's move to a presidential system.
In the April 2017 referendum, Turkish voters had approved the switch from a parliamentary system to a presidential one.
Under the changes, the number of lawmakers in parliament increases to 600 from 550, presidential and parliamentary elections would be held every five years, and the country's president is allowed to retain ties to his/her political party. The prime ministerial post has also been abolished.
Both in presidential and parliamentary elections, 59,391,328 electorates, including 56,342,263 in Turkey and 3,049,065 abroad, will go to polls in the elections.
Voting will be held from 8 a.m. to 5 p.m. local time across the country.
Political parties must submit their list of parliamentary candidates to Turkey's Supreme Election Council (YSK) by May 21.
Voting at foreign missions and custom gates will begin on June 7.
Firsts in political history
For the first time in Turkish political history, political parties will go to election by forming alliances. Also, mobile ballot boxes, presidential candidate with 100,000 signatures and the fact that presidential and parliamentary elections both would be held on the same day are some of the firsts in this election process.
Turkey's ruling AK Party and MHP will enter the race as an alliance while CHP, IYI Party, SP and DP will participate as part of the other alliance.
