>> In a simple yes or no answer the tax have made that choice. The votes are being counted in this historical referendum which will decide whether President Erdogan will be granted sweeping new powers. In this province in the mainly Kurdish South East of the country, many fear if Erdogan wins it could lead to greater authoritarianism.
The divided country is riffed with political differences. Nearby, three people were shot dead at a polling station, reportedly during a dispute over how they were voting.

Opinion polls suggested a narrow lead for yes in the run up to the vote.
Reuters' David Dolan is in Istanbul.>> In the days running up to the vote, opinion polls were putting the yes camp at a slight margin, 51%, 52%. And the numbers that we're seeing now at 54% probably jibe with that, in the sense that we're starting to see more votes come in from eastern Turkey, from southeast Turkey, which are boosting the no camp.
So of course, southeast Turkey's mainly Kurdish and there would be a lot of supporters of the no camp in that part of the country. So we are still watching. There, of course, not all the votes are tallied and there's been no final declaration. But as I said, with 3 quarters in, we're looking at 54% backing the yes vote.

Those voting yes believe their country would be more stable amid Turkey's security challenges following an aborted coup nine months ago and to avoid the fragile coalition governments of the past
