A key Iranian reform leader says he will run in next month's presidential elections, four days after a ban on his candidature was lifted. Former Education Minister Mostafa Moin's decision was announced today in a statement read out at a meeting of his Islamic Iran Participation Front -- the largest reformist party in the country. On Wednesday, Iran's Guardian Council reversed a decision to bar Moin from running after Supreme Leader Ayatollah Ali Khamenei urged the body to reconsider. In his statement, Moin said he had considered boycotting the polls but becided to run in order to defend what he called "the rights of the silent majority." There are now seven candidates running in the June 17 polls, with former President Akbar Ashemi Rafsjanjani considered the favourite.
