TEHRAN, Jan. 20 (Xinhua) -- Iran's ex-president Seyed Mohammad Khatami said that he has not made a final decision to rerun for presidency in June, local students news agency ISNA reported on Tuesday.

    Khatami in the country's reformist camp made the remarks while commenting on the possibility of his rerun for the next presidency, according to ISNA.

    "It is better to make a unity around a thought or an idea rather than a person," Khatami was quoted as saying, adding "I hope to make a final decision in the following days."

    Earlier on Tuesday, the semi-official Fars news agency reported that Khatami "eventually announced his candidacy for the upcoming presidential elections in June."

    Observers said that Khatami, as a reformist president from 1997 to 2005, failed to bring and institutionalize significant social and political changes to the country.

    Mehdi Karoubi, former parliament speaker and head of reformist Etemad-e Melli (national confidence) party, also decided to run for presidency.

    After losing ground to conservatives in 2005 presidential elections, the reformist camp has made attempt to revitalize its ranks for a strong reappearance in the country's political arena.

    Khatami has criticized the "aggressive policies" of current President Mahmoud Ahmadinejad, saying that "aggressive and blistering rhetoric plays into the hands of the enemy, harming the country and the system."

    Ahmadinejad has not yet declared whether he would seek a second term in June.
