Turkey holds elections every five years. Presidential candidates can be nominated by parties that have passed the 5% voter threshold in the last parliamentary election, or those who have gathered at least 100,000 signatures supporting their nomination.

The candidate who receives more than 50% of votes in the first round is elected president, but if no candidate gets a majority vote, the election goes to a second round between the two candidates who received the highest number of votes in the first round.

Parliamentary elections take place at the same time as the presidential elections. Turkey follows a system of proportional representation in parliament where the number of seats a party gets in the 600-seat legislature is directly proportional to the votes it wins.

Parties must obtain no less than 7% of votes – either on their own or in alliance with other parties – in order to enter parliament.

The vote will take place Sunday, with candidates casting their ballots for both elections at the same time. The second presidential ballot, if it takes place, will Polls open on at 8:00 a.m. local time (1 a.m. ET) and close at 5 p.m. (10 a.m. ET). Results are expected after 9 p.m. (2 p.m. ET) local time.
