The Etemad-e Melli website said Karoubi made the call in a letter to parliament speaker Ali Larijani, who has dismissed Karoubi’s rape allegations last week as “baseless.”
The meeting should be attended by Larijani, President Mahmoud Ahmadinejad, judiciary chief Ayatollah Sadeq Larijani, former president Akbar Hashemi Rafsanjani and the state prosecutor, Karoubi said.
“I ask you to organize a meeting … in which I can personally present my documents and evidence over the cases of sexual abuse in some prisons,” Karoubi said in the letter.
“I am waiting for your quick and rational action,” he added.
Karoubi, who came fourth in the disputed June 12 presidential election, has come under fire from hardliners for saying some protesters, both men and women, were raped in jail.
