Iranian President Mahmoud Ahmadinejad has suffered a political setback after supporters of his rival, Clerical Supreme Leader Ayatollah Ali Khamenei, won more than 75 percent of seats in parliamentary elections. The election is likely to increase chances Ahmadinejad will be viewed as a lame duck president ahead of next year’s presidential elections. Many supporters of Ahmadinejad lost their parliamentary seats, including his sister, Parvin Ahmadinejad.
