BAGHDAD (AFP) - Iraqi politicians are reviewing a rejected bill on provincial elections and will return it to parliament with fresh suggestions within 48 hours, a senior official said on Saturday. Sheikh Khalid al-Attiya, the deputy speaker of parliament, said two committees attached to the lawmaking body were reviewing the controversial draft rejected on Wednesday by the three-member Presidency Council. "I hope a compromise formula that satisfies all the parties will be found," Attiya told AFP. "The two committees and the deputies are committed to presenting a final report to the parliament in the next 48 hours." Iraq's 275-member parliament on Tuesday initially adopted the provincial election law that would have allowed provincial polls scheduled for October to proceed. The United States is keen for the election to take place, as it believes it legitimises Iraq's fledgling political process and aids national reconciliation among the country's warring factions. But the bill faced strong opposition with major blocs in parliament - mainly Kurds and some Shia ministers - storming out in protest and leaving only about 140 MPs to vote. The controversy prompted the Presidency Council, which includes President Jalal Talabani and two deputies who have the right to veto bills, to reject the draft and return it to parliament for reworking. The Presidency Council said parliament's passing of the law had violated procedures enshrined in the constitution, namely the ballot had been held in secret. However, the key dispute in the legal wrangle is over how to constitute the provincial council of Kirkuk, the northern oil province claimed by both the Arabs and Kurds.
