Turkey's ruling Justice and Development (AK) Party on Tuesday submitted an extraordinary appeal to the Supreme Election Council (YSK) over the results of mayoral poll in Istanbul.
"We have suspicions [about Istanbul's elections] and we still were not able to resolve these doubts," said Ali Ihsan Yavuz, AK Party's deputy chairman.
He added that only the YSK could resolve this doubt.
According to unofficial results Ekrem Imamoğlu led the Istanbul mayoral race with 48.79% of the vote prior to all recounts, ahead of AK Party's Binali Yıldırım at 48.51%.
Contesting the results after "organized irregularities" surfaced, AK Party has asked for a recount, saying this may change the results.
