National parliamentary elections will be held Jan. 30, Iraqi officials announced Monday, sliding the date into next year in a move that could complicate the US timetable for drawing down its forces. The new parliament will choose a prime minister and Cabinet, a process that could take months. A long and turbulent delay in setting up a new government could force President Barack Obama to revise his goal of removing most of American troops from Iraq by the end of August 2010. Prime Minister Nouri al-Maliki will be hoping to build on his success in last January's provincial balloting to form a strong government capable of dealing with the security and economic challenges facing this country as the American role fades. But a recent spate of deadly bombings in Baghdad has tarnished his image, and the threat of more violence could rise as US forces redeploy outside of urban areas by June 30 as scheduled. The election for the 275-member parliament had been expected in December, four years after the current assembly was chosen. But the current parliament did not hold its first session until March 2006, or about three months after the December 2005 election.
