The Turkish president said on Saturday they had taken all precautions to ensure security during Sunday's elections.
Speaking at an election rally in Istanbul's Esenyurt district, Recep Tayyip Erdogan said: "We have taken foolproof measures."
He added that representatives from every party will be present inside the polling stations.
Erdogan slammed main opposition Republican People's Party (CHP) presidential candidate Muharrem Ince for saying that he will sleep in front of the Supreme Election Council.
"Mr. Muharrem, we are living in a state of law," he said, adding that Ince's statement implied he had understood that he will lose the election.
He also added that Turkey is not taking dictation on foreign policy anymore, but is active both on "the table and the ground".
