A comeback by Mousavi may have an overwhelming effect on Iranian politics. He served as prime minister during a time of crisis -- the Iraq-imposed war on Iran.
Hedayat Aqayi, who sits on the Kargozaran head council, added that should Mousavi enter Iran's 10th presidential election, he would enjoy the support of both the Reformists and the Principlists.
President Ahmadinejad is expected to seek a second term.
Khatami has recently said that he needs more time to evaluate the situation in the political arena before deciding whether to seek the presidency for a third time.
Should he decide to run for office, the former Iranian president will face Mehdi Karroubi, a member of Iran's National Confidence Party and the only person to have announced his candidacy in the upcoming presidential election.
