Following the ratification of the Constitution of Iraq on October 15 2005, a general election was held on 15 December to elect a permanent 275-member Iraqi Council of Representatives.
The elections took place under a list system, whereby voters chose from a list of parties and coalitions. 230 seats will be apportioned among Iraq's 18 governorates based on the number of registered voters in each as of the January 2005 elections, including 59 seats for Baghdad Governorate
The seats within each governorate will be allocated to lists through a system of Proportional Representation. An additional 45 "compensatory" seats will be allocated to those parties whose percentage of the national vote total (including out of country votes) exceeds the percentage of the 275 total seats that they have been allocated. Women will be required to occupy 25% of the 275 seats
The change in the voting system will give more weight to Arab Sunni voters, who make up most of the voters in several provinces. It is expected that these provinces will thus return mostly Sunni Arab representatives. The nationwide vote of the previous election meant that the low voter turnout among Sunni Arabs was overwhelmed by the high turnout of the Arab Shi'ites and the mostly Sunni Kurds. In the previous election the largest Sunni Arab block received only 5 seats. Arab Sunni parties withdrew from the elections so late that they could not be removed from the voting lists. The election was boycotted by most Sunni Arabs.
Turnout for the election was reported to be high, at 70%. The White House was encouraged by the relatively low levels of violence during polling,
with one insurgent group making good on a promised election day moratorium on attacks, even going so far as to guard the voters from attack.
President Bush frequently points to the election as a sign of progress in rebuilding Iraq.
Final uncertified results were released by the Independent Electoral Commission of Iraq on Friday 20 January 2006. Certified results are expected to be released within two weeks, after the adjudication of any appeals and after lists have submitted the names of people who will take the seats.

After six months of negotiations a "government of national unity" was agreed between the United Iraqi Alliance, Iraqi Accord Front, Kurdistani Alliance and Iraqi National List, under the leadership of Prime Minister Nouri al-Maliki.
According to an interview with Rajaa al-Bhayesh, a political scientist at Baghdad's Mustansiriya University, fear of wider civil conflict -- beyond the likely continuation of violence by fringe groups like al Qaeda -- is likely to promote the spirit of compromise.
The emerging Iraqi political scene has been marked by groups of established parties running on joint lists, often grouped on sectarian or ethnic grounds. These lists are not necessarily stable, as the parties sharing a list may be past or present rivals; the situation will be even more complicated for the December 2005 election because parties can form different alliances in different governorates. The landscape is currently fluid; what follows is a list of some of the more important parties and coalitions, with a focus on alliances that have shifted since the January 2005 election.
In advance of the December 2005 elections, Moqtada al-Sadr's party chose to join the Alliance. However, the Iraqi National Congress and Iraqi Hezbollah left the Alliance to form their own lists.
In a blow to the Alliance, Ayatollah Ali al-Sistani announced that he would not back any particular party for the election; he merely encouraged people to vote "according to their beliefs." He is said to have been disappointed with the performance of the transitional government.
It was initially reported before the election that the UIA seats would be split between the parties as follows:
Analysis of the seat allocation after the elections showed that the 109 district seats and 19 compensatory seats won by the UIA were split as follows:
This coalition will also contest the December elections, but the smaller Kurdistan Islamic Union, who won 10 percent of the seats in the Dahuk and Sulaymaniyah governorate elections in January, has announced that it will form its own governmental lists.
For the December 2005 election, it has joined forces with former interim President Ghazi al-Yawar's The Iraqis list, the People's Union list (which is dominated by the Iraqi Communist Party), and the Sunni Arab politician Adnan Pachachi and his Assembly of Independent Democrats to form a single list called the Iraqi National List. This list will attempt to present a secular and trans-community alternative to the other major lists, which are more based on the support of a single ethnic or religious groups.
However, the Association of Muslim Scholars, which is influential in the Sunni community, has called for a boycott of the December elections, which could have an adverse impact on the Iraqi Accord Front's success.

On December 22 2005 Sunni Arab and secular Shiite factions demanded that an international body review election fraud complaints, and threatened to boycott the new legislature. The United Nations rejected the idea.
Large demonstrations broke out across Iraq on December 23, 2005 to denounce the parliamentary elections. Protesters said that the elections were rigged in favor of the main religious Shiite coalition. Many Iraqis outside the religious Shiite coalition allege that the elections were unfair to smaller Sunni Arab and secular Shiite groups. As many as 20,000 people demonstrated after noon prayers in southern Baghdad. Over 2,000 people demonstrated in Mosul, accusing Iran of involvement in the election.
Sheik Mahmoud al-Sumaidaei of the Association of Muslim Scholars, a major Sunni clerical group, told followers during prayers at Baghdad's Umm al-Qura mosque that they were "living a conspiracy built on lies and forgery."

Violence grew over the controversial election results. Car bombings and attacks on US and Iraqi officials continued after the elections. In Mosul Qusay Salahaddin, a Sunni Arab student leader was abducted and killed after leading a demonstration against the election results. Some 2,000 fellow students gathered at the mosque where Salahaddin's body was taken. Sunni's quickly accused militia forces loyal to one of the main parties in the Shiite Alliance bloc for Salahaddin's death. No group has yet claimed responsibility for the murder.
