Erdogan took a comfortable lead of almost five points over his rival in the first round. The election will determine who will govern Turkey, a NATO member state of 85 million people. Turkey is the world's largest refugee-hosting country, with about 5 million migrants, including 3.3 million Syrians. The pro-Kurdish Peoples' Democratic Party (HDP) won 2.2 percent of the vote in this month's parliamentary elections. The Zafar Party won 5.17% of the votes.
