Mohammed Ali Abtahi visiting Mehdi Karroubi during House Arrest
After the announcement of the election results, Karroubi alleged that a network of mosques, the Revolutionary Guard Corps, and Basij militia forces had been illegally used to generate and mobilize support for Ahmadinejad. He then explicitly alleged that Mojtaba Khamenei, a son of the Supreme Leader Ayatollah Khamenei, was among the conspirators. Ayatollah Khamenei wrote to Karroubi, characterizing these allegations as “below his dignity” and warning that they would “result in a crisis”, which he would not allow. Karroubi responded in an open letter, resigning from all his political posts, including that as adviser to the Supreme Leader and as a member of Expediency Discernment Council, both of which he had been appointed to by Khamenei.
