Millions of Turkish voters went to polls on Sunday to elect the country's next president and members of its 600-seat parliament.
The first round of voting ended with no candidate able to clear the required 50% threshold, but incumbent President Recep Tayyip Erdoğan took the lead, said Ahmet Yener, head of the Supreme Election Council, citing unofficial results.
Erdoğan finished the first round with 49.51% of the vote, while his closest competitor Kemal Kılıçdaroğlu, leader of the main opposition Republican People's Party (CHP), came second at 44.88%, Yener said.
Sinan Oğan of the ATA (Ancestral) Alliance got 5.17%, while Muharrem Ince, who withdrew from the presidential race late last week after ballots had already been printed, got 0.44%, Yener added.
As no candidate was able to win an outright majority in Sunday's vote, a second-round runoff will be held on May 28.
Voter turnout in Sunday's elections was 88.92%, with turnout from Turkish citizens abroad at 52.69%, Yener said.
As for parliamentary elections, the People's Alliance, led by Erdoğan's Justice and Development (AK) Party, and the Nationalist Movement Party (MHP), are poised to secure a majority of seats in the Turkish parliament after Sunday's polls.
