HaberTurk and other Turkish broadcasters said the results, given less than two hours after polling stations closed, were based on 9.1% of the ballot boxes counted, Reuters reported.

The head of Turkey's High Election Board earlier lifted a publication ban and said to wait until it announces official tentative results later.

Pre-election polls had given the edge to Kilicdaroglu, who pledges to roll back much of Erdogan's two-decade legacy.
