 A group of Iranian clerics has issued an anonymous letter calling Iran’s supreme leader a dictator and demanding his removal, the latest and perhaps strongest rhetorical attack on him yet in the country’s post-election turmoil.

While the impact of the clerics’ letter, posted late Saturday on opposition Web sites, may have been diluted by the withholding of their signatures, two Iranian experts vouched for its authenticity. Its publication followed other unusual verbal attacks on the leader, Ayatollah Ali Khamenei, in recent days.

Last week a group of former lawmakers issued their own letter calling his qualifications into question. A day earlier, a member of the state body empowered to dismiss Ayatollah Khamenei called for an “emergency meeting” to address criticisms.

The letters do not pose any real threat to Ayatollah Khamenei, who retains the loyalty of the security services and most of the political elite. The clerical establishment is heavily dependent on him, and scarcely any member would dare challenge him openly.
