Turkey's electoral authority has released the official tally of the referendum on expanding presidential powers, confirming a narrow win for President Recep Tayyip Erdogan's "yes" camp.
Sadi Guven, the head of the High Electoral Board, told reporters that the "yes" side received 51.41 per cent of the votes in the April 16 referendum, while the "no" votes garnered 48. 59 per cent.
Guven said: "our board declares that the constitutional amendments have been accepted."
The opposition contested the April 16 referendum on the grounds that the decision to count ballots without the official stamps was illegal and allowed for fraud.
