The US is concerned about the 'quality' of Turkey’s democracy, acting US Department of State Mark Toner said.
"These are discussions that we have on a somewhat regular basis with the Turkish Government. We’re looking at that and studying it very closely, and hope that the referendum is carried out in such a way that guarantees and strengthens democracy in Turkey," he said at a briefing on Thursday.
The April 16 vote will decide on the biggest change in Turkey's system of governance since the modern republic's foundation almost a century ago, potentially replacing its parliamentary system with an executive presidency, Reuters recalls.
