'Yes' on 57 percent with half of ballots counted - Anadolu

ANKARA (Reuters) - Votes in favour of Turkish constitutional changes that could give President Tayyip Erdogan sweeping new powers stood at 57 percent with just over half of ballots counted, the state-run Anadolu news agency said on Sunday.

Data cited by Anadolu showed a high percentage of "Yes" votes in central Anatolia, while "No" votes led in coastal regions near the Aegean Sea and Turkey's mainly Kurdish southeast.
