The voting process for 56.3 million registered citizens will be held between 8 a.m. and 5 p.m. local time at 180,065 ballot boxes in all 81 provinces of Turkey.
Some 1.65 million registered citizens will be casting their first votes in the snap election, which will herald a switch to a new powerful executive presidency narrowly approved in a controversial referendum last year, marred by allegations of fraud.
Turkish presidential candidate Muharrem Ince, the main challenger to President Recep Tayyip Erdogan in Turkey's June 24 presidential election, held a campaign rally in Istanbul on the eve of the election, in front of thousands of supporters.
For the first time, the presidential and parliamentary ballots will be placed in a single envelope.
Turkey's presidential and parliamentary elections, to be held this Sunday 24 June 2018 , are probably the most crucial elections the country has ever had.
