Tehran:
Iran began voting today to elect the successor of President Mahmoud Ahmadinejad, the state television announced.
The vote pitches a divided conservative camp against a moderate candidate who enjoys the backing of the reformists.
Some 50.5 million people are eligible to vote for a successor to Ahmadinejad, who is constitutionally barred to run for a third term.
Iran has been isolated internationally under his presidency over its controversial nuclear drive.
The polls will remain open for the next 10 hours, though voting may be extended until midnight, if the interior ministry decides that it is necessary.
