Members of the Council of Representatives are elected through the open list form of party-list proportional representation, using the 18 governorates of Iraq as the constituencies. The counting system uses the modified Sainte-Laguë method with a divisor of 1.7 which is considered as a disadvantage to smaller parties. Eight seats remain reserved for minority groups at the national level: five for Christians and one each for Mandaeans, Yazidis, and Shabaks. However, the Council of Representatives voted on 11 February 2018, to add an extra seat for minorities, in the Wasit Governorate for Feyli Kurds, making the total number of parliamentarians equal to 329.In January, the Supreme Court ruled that the representation for Yazidis should be increased, although it’s unclear whether this change will be implemented in time for these elections.
