Tehran, Iran -- Iran state television says polls have opened in the election that will determine a successor to President Mahmoud Ahmadinejad.
More than 50 million eligible voters are choosing among the six candidates who remain in the race: a moderate, four conservatives and a hard-liner. All are loyal to Supreme Leader Ayatollah Ali Khamenei, who has final say on all state matters.
Cleric Hasan Rowhani has moved to the forefront as the moderates' choice after another pro-reform candidate pulled out on Tuesday.
Ahmadinejad cannot run for a third consecutive term in office.
