From the Document: "Iraq held a national election on October 10, 2021, with voters selecting 329 members for the unicameral legislature, the Council of Representatives (COR). The COR elects Iraq's president and approves the prime minister's program and cabinet nominees. The election results will inform negotiations among political groups to identify the new COR's 'largest bloc,' which nominates the prime minister. The largest bloc may or may not include the coalition or party that won the most COR seats. Past government formation talks have taken months to resolve. [...] For the United States, the election result could reduce the formal influence of Iran-aligned groups who seek to revise or rescind plans for a continued U.S. military advisory presence in Iraq after December 31, 2021. However, Iraqi analysts expect a compromise coalition government to emerge that includes or reflects the interests of Iran-backed groups alongside their more electorally successful rivals. Such a government could lower the risk of political violence, but also may make systemic reforms less likely."
