Iranian leaders were looking for a high turnout at Friday's poll to ease a crisis of legitimacy caused by Ahmadinejad's re-election in 2009, when widespread accusations of fraud plunged the Islamic Republic into the worst unrest of its 33-year history. Iran also faces economic turmoil compounded by Western sanctions over a nuclear programme that has prompted threats of military action by Israel, whose leader meets US President Barack Obama in the White House on Monday. The vote in Iran is only a limited test of political opinion since leading reformist groups stayed out of what became a contest between the Khamenei and Ahmadinejad camps. "Whenever there has been more enmity towards Iran, the importance of the elections has been greater," Khamenei, 72, said after casting his vote before television cameras. "The arrogant powers are bullying us to maintain their prestige. A high turnout will be better for our nation and for preserving security." His hopes for wide participation received a boost when Iranian authorities had to delay the end of voting by five hours to let more people cast their ballot, closing polling stations at 11 p.m. (1930 GMT) on Friday. Iranian media say the turnout was over 65 percent. Ballots are counted manually and Iranians may have to wait three days for full results. Some media reports suggested that rivals of Ahmadinejad won in some constituencies. The semi-official Mehr news agency said the president's sister Parvin Ahmadinejad failed to secure a seat in the parliament. She was running from the central town of Garmsar, the home-town of Ahmadinejad. Pro-reform candidate Mohammadreza Tabesh was elected from the birth place of moderate former president Mohammad Khatami. Results in major cities like Tehran have not been announced yet. The vote will have scant impact on Iran's foreign or nuclear policies, in which Khamenei already has the final say, but could strengthen the Supreme Leader's hand before the presidential vote next year. Ahmadinejad, 56, cannot run for a third term. Iranians may be preoccupied with sharply rising prices and jobs, but it is Iran's supposed nuclear ambitions that worry the outside world. Western sanctions over the nuclear programme have hit imports, driving prices up and squeezing ordinary Iranians.
