BAGHDAD (Reuters) - Iraqi Prime Minister Nuri al-Maliki said on Saturday he would form a government by mid-December that would incorporate all political factions, including rival Iyad Allawis Iraqiya bloc. President Jalal Talabani formally asked Maliki on Thursday to form a government, giving him 30 days to choose a cabinet from fractious Shiite, Sunni and Kurdish political factions. I will not let time go by until the period ends. I have a time ceiling that doesnt exceed between the 10th and the 15th of next month, Maliki said at a news conference in Baghdad, his first since being formally appointed. Maliki, a Shiite, won a second term as prime minister in a power-sharing deal reached with rivals on November 10 that gave the presidency to Talabani, a Kurd, and named Iraqiya lawmaker Osama al-Nujaifi, a Sunni, to the post of speaker of parliament. Maliki said the Sunni-backed, cross-sectarian Iraqiya bloc would be a main partner in the new government, whether Allawi participated or not. The power-sharing deal gave Allawi, who wanted Malikis job, the leadership of a yet-to-be-created council for strategic policies. Allawi, a former prime minister, has since criticized the deal, which ended an eight-month impasse following a March parliamentary election that failed to produce a clear winner. The non-participation of a person doesnt stop the cycle of forming the government ... we will welcome anyone who wants to be a partner, Maliki said. Iraqiya will be a main partner in forming the government.
