Turks are voting in the most pivotal elections in their modern history, to decide if Recep Tayyip Erdogan remains president after 20 years in power.
His main rival, Kemal Kilicdaroglu, promises to scrap many of the powers acquired by President Erdogan after he survived a failed coup in 2016.
Buoyed by a broad opposition alliance, he has a real chance of winning.
But this race has become so intense and the stakes so high that campaigning went up to the wire.
To secure outright victory on Sunday, the winner needs more than 50% of the vote. Otherwise it goes to a run-off in two weeks’ time.
