Former Iranian President Mohammed Khatami announced he will not run for president in the 2009 election, despite his popularity as a reformist candidate, following a scandal over an incident in Italy when he shook hands with a woman.
Such handshakes are generally forbidden under Islam except for between family members. Khatami denied the incident took place even as a video circulated on YouTube.
Radical clerics have circulated a petition calling for Khatami to be defrocked, and posters of Khatami have been defaced. Supporters see his decision to not run as capitulation to extremists.
