The first government of Iraq led by Nouri al-Maliki took office on May 20, 2006 following approval by the members of the Iraqi National Assembly. This followed the general election in December 2005. The government succeeded the Iraqi Transitional Government which had continued in office in a caretaker capacity until the new government was formed and confirmed.
After some disputes over the election results, the members of the new Council of Representatives were sworn in on March 16, 2006. In the meantime, negotiations over the forming of a government had begun. Leaders of the four largest political groupings called for a government of national unity. Although it was decided in advance that the largest grouping (the United Iraqi Alliance) would name the Prime Minister, this decision would prove to be hot matter, both within the Alliance and in the negotiations with other groupings, who rejected the first nominee, incumbent Prime Minister Ibrahim al-Jaafari. Finally the Alliance reached a decision to nominate Nouri al-Maliki to the post.
In December 2006, media reported a plot to oust Maliki in a no-confidence vote and to create a new governmental alliance between SCIRI, UIA independents, the Kurdistani Alliance and Iraqi Islamic Party. Adil Abdul Mahdi had been proposed as the new Prime Minister, but SCIRI MP Hameed Maalah was quoted saying the groups hadn't yet agreed on a new leader. A Maliki aide confirmed the plot but said they intended to sabotage it. A no-confidence vote would require a simple majority but a new Prime Minister would require a two-thirds majority.
