A group of Iranian MPs have filed a complaint to the judiciary against opposition leader Mir Hossein Mousavi over post-election violence, the Fars news agency reported on Sunday, quoting a lawmaker. “We submitted this complaint against Mousavi's radical moves to the judiciary a few weeks ago,” Mohammad Taghi Rahbar, a hardline member of parliament's judicial commission, told Fars. “We expect it to be examined as soon as possible,” he said, without specifying how many lawmakers had backed the action. “Those who issued statements and directed recent riots should be accountable for the bloodshed and go on trial,” he added. Iranian authorities have tightened pressure on their opponents by staging what former President Mohammad Khatami derided on Sunday as a “show trial” of 100 reformists accused of trying to instigate a “velvet revolution”. Mousavi said that confessions made by protesters at a closed-door trial were made after they were put through “medieval-era torture.” The trial was the latest shot in an official campaign to snuff out defiance by those who say Iran's June 12 election was rigged to ensure the re-election of President Mahmoud Ahmadinejad, due to be sworn in by parliament on Wednesday. “The scenes that we saw were a clumsy preparation for the launch of the 10th government,” Mousavi said on his website. Supreme Leader Ayatollah Ali Khamenei, who has endorsed the election result and demanded an end to protests, will formally approve the hardline incumbent for a second term on Monday. Khatami, several of whose close associates were in the dock on Saturday, said the trial violated Iran's constitution. “Such show trials will directly harm the system and further damage public trust,” he said on his website (www.khatami.ir). The mass trial of dozens of reformists, including senior officials such as Khatami's former vice-president, Mohammad Ali Abtahi, paraded in prison dress without his clerical turban, has no precedent in Iran's 30-year history. Proceedings were closed to all but state media. On Sunday, Ahmadinejad's media adviser and close ally, Ali Akbar Javanfekr, made public his resignation, which local media said had been offered two weeks ago but not accepted. After his inauguration, Ahmadinejad has two weeks to submit his cabinet list to the mostly conservative parliament, which may resist if he only names members of his inner circle. Meanwhile, ten more protesters who opposed the re-election of President Mahmoud Ahmadinejad were put on trial in a revolutionary court in Tehran on Sunday, the ISNA news agency reported. Defeated Iranian presidential candidate Mohsen Rezai called the prosecution of members of the security forces behind attacks on vote protesters, the Mehr news agency reported.
