Turkish President Recep Tayyip Erdogan and the ruling political party he leads on Sunday secured victory in the country’s first-ever parallel presidential and parliamentary elections.

With over 90 percent of the vote counted, Mr. Erdogan defeated opposition candidate Muharrem Ince, securing 52 percent of the country’s presidential ballots, with Mr. Ince garnering over 30 percent of the vote. Mr. Ergodan’s political coalition, led by his Justice and Development Party (AK Party) also won control of the country’s legislative branch, soundly defeating Mr. Ince’s opposition Republican People’s Party’s (CHP) Nation Alliance by locking in over 53 percent of the parliamentary vote to CHP’s 34 percent, according to unofficial tallies taken by Turkish news agency Anadolu.

Over 56 million Turkish citizens were registered to vote in the historic election, which for the first time put control of the parliament and the presidential palace on the same ballot.

While Turkey’s Supreme Election Council has yet to validate the vote tallies and announce an official winner in either the presidential or parliamentary races, Mr. Erdogan and his AK Party claimed victory in the early hours of Monday morning. “The unofficial results of the elections have become clear. According to these … I have been entrusted by the nation with the task and duties of the presidency,” he told reporters from party headquarters in Istanbul.

Despite messages of congratulations for Mr. Erdogan from regional and world leaders, CHP party leaders refused to concede, arguing that Mr. Erdogan or his party could still fall short of the required 50 percent majority threshold. That would trigger a July 8 runoff.
