Turkey's main opposition was leading with 53.6% of votes versus 45.4% for President Tayyip Erdogan's AK Party in Istanbul's high-stakes re-run mayoral election, with nearly 95% of the city's ballots opened, CNN Turk said on Sunday.
The Istanbul mayoral candidate for the ruling Justice and Development (AK) Party Binali Yıldırım on Sunday congratulated his rival Ekrem İmamoğlu for his lead in the election as results started trickling in.
