merging districts to form electrol districts

According to the constitution the Parliament should consist of 225 seats (members) 1. 36 seats were allocated to the nine provinces, four each (section 96(4)). A delimitation commission would apportion the four seats between the electoral districts in each province. 2. 160 seats were allocated to the electoral districts (section 98). An election commission would apportion the seats annually based on the number of registered electors. 3. 29 seats were reserved for the national list (section 99A).
