Sunni

Based on the provided articles, "Sunni" refers to a political bloc within the Iraqi parliament. The articles highlight the ongoing political negotiations in Iraq following recent elections, particularly concerning the selection of a new president and prime minister. The Sunni bloc's approval is crucial for any candidate nominated by the Kurdish parties to gain the presidency. The election of the parliament speaker, Haybat al-Halbousi from the Taqaddum (Progress) Party, is a significant step in government formation, but the process is facing delays and US pressure. Concerns exist that the return of Nouri al-Maliki as prime minister could escalate sectarian tensions. The Sunni bloc's role in these negotiations is therefore highly relevant, as their decisions will significantly impact the future political landscape and stability of Iraq.
