Iran's non-elected constitutional watchdog Wednesday approved the result of presidential runoff election that gave Mahmoud Ahmadinjead a landslide victory against his rival Ayatollah Hashemi Rafsanjani, state-run television reported. Ayatollah Ahmad Jannati, head of the Guardian Council, said in a letter addressed to Interior Minister Abdolvahed Mousavi Lari Wednesday that the council approved the outcome of runoff vote held Friday since no complaints were filed by any of the candidates. Ahmadinejad, the mayor of Tehran, trounced Rafsanjani, one of Iran's best known statesmen, to win Iran's presidential election runoff. The results gave Ahmadinejad 61.6 percent of the vote to Rafsanjani's 35.9 percent. Turnout among Iran's approximately 47 million eligible voters was more than 59 percent.
