Turkey's main opposition party has filed a formal request seeking Sun.
"It is clear that the High Electoral Board is not receiving its power from the people, the law or the constitution but rather from a specific centre, a specific political authority", CHP leader Kemal Kilicdaroglu said in a speech, accusing the body of "changing the rules mid-game".
"Therefore we do not have any difficulties on that front", Erdogan said.

Sancar went on to state that the electoral board's last-minute decision to allow unstamped ballots had prevented proper record-keeping to occur, meaning it was now impossible to determine how many invalid or make votes may have been counted.

"We will follow closely how Turkey behaves on this".
Thousands took to the streets in Istanbul, Ankara and elsewhere in Turkey to protest the results of the referendum.
Erdogan has dismissed the criticism from the observer mission, telling the monitors that they should "know your place".
European officials have firmly declined to congratulate Erdogan's win, unlike the US president.
