Turkey has been voting on constitutional reform in a referendum seen as a test of support for Prime Minister Recep Tayyip Erdogan.
He says the changes are needed to strengthen democracy and bring the EU candidate country closer to European norms.
But critics claim it is all about the ruling AK Party increasing its powers, notably over the judiciary. The secular establishment accuses Erdogan of harbouring Islamist ambitions, something he denies.
In Diyarbakir, voter Mehmet Yildirimlar said he wanted the amendments passed in the interests of democracy.
“The country will be more prosperous and more transparent,. With these expectations, I came here to vote.”
But, stressing the importance of an independent judicial system in democratic countries, Ankara resident Buke Acar said she voted ‘no.’
A late opinion poll showed a majority of Turks backing the government’s package. Other voter surveys said it was too close to call. Results are due in shortly.
