الحكومة العراقية الانتقالية
The IIP led a large-scale public campaign urging Iraqis (especially the Sunnis) to vote against the constitutional referendum in 2005. Two days before the referendum took place, the IIP announced its support for a "yes" vote, following a compromise with the members of the Iraqi Transitional Government whereby the newly elected Iraqi National Assembly would consider amendments to the constitution in 2006.
