Turkish President Recep Tayyip Erdogan appears to have failed to win a majority in Sunday’s presidential election, forcing him into a run-off against his main challenger, Kemal Kilicdaroglu, two weeks from now.

With 93% of the vote counted, Erdogan had 49.6% of the vote, just under the 50% threshold for victory.

Under Turkish law, no candidate can be elected president without winning a majority of the vote. If no candidate wins a majority, the top two candidates will face each other in a run-off election in two-weeks.

Erdogan has been in power since 2003. He has been a controversial figure, both domestically and internationally. He has been accused of authoritarianism and of cracking down on dissent.
