TEHRAN (Reuters/AFP) - Irans highest legislative body said on Saturday it was ready to recount a tenth of the votes in a disputed presidential election. Supreme Leader Ayatollah Ali Khamenei told protest leaders on Friday that they would be responsible for any bloodshed if rallies continued against the election, which he said President Mahmoud Ahmadinejad had won fairly by 11 million votes. The 12-man Guardian Council, which must certify the result of the election, announced plans for a partial recount. Although the Guardian Council is not legally obliged ... we are ready to recount 10 per cent of the (ballot) boxes randomly in the presence of representatives of the three (defeated) candidates, a Council spokesman said. The Council had invited defeated presidential candidates Mir Hossein Mousavi, Mehdi Karoubi and a third candidate, Mohsen Rezaie, to raise their complaints at a special session. But only Rezaie, a conservative who is a former Revolutionary Guard commander, attended. Irans President Mahmoud Ahmadinejad, thanked Supreme Leader Ayatollah Ali Khamenei, who has sided with his disputed re-election, for helpful comments he made at Friday prayers, news agencies reported on Saturday. Siding with Ahmadinejad in his first public appearance since the vote, Irans Supreme Leader on Friday ruled out major fraud in the June 12 election which has been contested by three other candidates. As a small child and chosen server by the great Iranian nation, I feel I need to cordially thank you for the good decision... in Tehran Friday prayers and making helpful comments and powerfully announcing the peoples rightful stances on important issues of the day, Ahmadinejad said in a message to Khamenei carried by several local news agencies, including ILNA. Khamenei said on Friday: The people have chosen whom they wanted. He said there could be no doubting Ahmadinejads re-election. The legal mechanisms in our country do not allow cheating. How can one cheat with a margin of 11 million votes? he asked. The former prime minister Mousavi told his supporters he was ready for martyrdom, a Mousavi ally told Reuters. In a public address in Jeyhun (a southwestern district of Tehran), Mousavi said he was ready for martyrdom and that he would continue his path, the ally, who asked not to be named, told Reuters by telephone from the Jeyhun street in Tehran. He urged Iranians to stage a nationwide strike if he was arrested by the authorities, a witness said. He called on people to go on a national strike if he gets arrested, the witness told Reuters. Mousavi harshly criticised Khameneis speech in which he ruled out any fraud in last weeks disputed election. In a statement issued on his newspaper website Kalemeh, he also said that his demand to cancel the result of the election is an undeniable right and vowed to side always with the Iranians to defend their rights. In a letter to electoral watchdog, the Guardians Council, Mousavi renewed his demand for a re-run of what he has called a shameful fraud of an election. All these counts of irregularities plus many others that were mentioned in previous letters ... are reasons to cancel the election nationwide, he said in the letter released on his campaign website, Ghalam News.
