Ankara (CNN) First results in Turkey's constitutional referendum began to filter out Sunday night after millions voted on controversial proposals to give sweeping new powers to the country's president, Recep Tayyip Erdogan. With 84.26% of the ballots counted, early results put the "yes" vote ahead, according to state-run news agency Anadolu. Results show 53.18% of Turks are in favor of giving Erdogan sweeping new powers and 46.82% are against. Erdogan, who cast his vote in Istanbul earlier in the day amid tight security, said he hoped Turks would make the "expected" choice. The cause of the clash was not immediately clear and it was not known if there was a connection to the referendum.
