Erdogan called a snap election in April, bringing the original poll date forward from November 2019. Recep Tayyip Erdogan is seeking to become the country's first president since the April 2017 referendum approved major constitutional changes which are set to come into force in these elections.
Other candidates include Muharrem Ince from the center-left Republican People's Party (CHP), Meral Aksener from right-wing IYI (Good) Party and Selahattin Demirtas, currently in prison, from the pro-Kurdish Democratic People's Party (HDP).
If no candidate receives an outright majority, the presidential poll will go to a second round on July 8.
