Mr Erdogan, who has been in power since 2003, is seeking a new five-year term with vastly increased powers under a new system and his ruling party is hoping to retain its majority in parliament.
Speaking early Monday, Supreme Election Council head Sadi Guven said 97.7 percent of votes had been counted and declared Erdogan the victor.

Meanwhile, Muharrem İnce has 30.8 percent of the votes, Meral Aksener 8.2 percent, and Selahattin Demirtaş 8.2 percent.
