The government knows the funeral is one demonstration it cannot forbid, says the BBC's Tehran correspondent Jon Leyne, although it fears it could spark another round of protests.The AP has more information:
Many people during Monday's funeral made references to the Green Movement of opposition leader Mir Hossein Mousavi, who joined the procession in Qom, witnesses said. Opposition leaders had called for people to turn out for a day of mourning, and Mousavi described Montazeri's death as a "great loss."Montazeri, it should be remembered, was one of the original leaders of the theological movement in parallel with Ayatollah Ruhollah Khomeini's revolutionary movement. But the famous falling out between Montazeri and Khomeini in 1989 and Montazeri's open contempt for the rise of (current) Supreme Leader Ayatollah Ali Khamenei 1997 made Montazeri a voice of reason in the face of dictatorship and a valued patron of the Opposition.
