Iran's hardline leaders have called for legal action to be taken against opposition leader Mir Hossein Mousavi over the post-election protests that have rocked the country.
Iranian authorities blame Mr Mousavi for the wave of violence that has killed at least 20 people since the disputed election on June 12.
Hardline parliamentarians and lawyers are now planning to write to judicial authorities complaining about the opposition leader's actions in encouraging the protests. They want him taken to court.
A student branch of the pro-government Basij militia, which helped suppress the protests, has supported the move.
Mr Mousavi rejects claims that he is to blame for the violence.
He still insists the election was rigged, and says the government of President Mahmoud Ahmadinejad is now illegitimate.
