The Independent Electoral and Boundaries Commission will from this month begin a review of constituencies and ward boundaries in the country.
IEBC Chairman Wafula Chebukati says the exercise will be based on population, geography and cultural aspects as provided in law.
The review which is conducted every 8 years is expected to conclude in the 2021.
Over the next four years the Independent Electoral and Boundaries Commission will embark on the delimitation of the 290 constituencies and 1,450 wards.
IEBC says it will lay emphasis on issues such as culture and population to determine if there will be need to either increase or decrease the number of legislative boundaries in the country.
Article 88(5) of the constitution states that the boundaries of each constituency shall among others take into account matters such as community interests, cultural ties as well means of communication.
Just like land Boundaries review is considered emotive, and some leaders are already calling for the split and renaming of some counties, constituencies and wards.
Last month Ameru Professionals proposed that Tharaka Nithi and Meru Counties be renamed to Meru South and Meru North Counties respectively.
Some leaders have also argued that their constituencies were too big, hampering effective resource distribution in the regions.
In Migori County a section of Kuria residents have called for a review of the county boundary arguing that their interests are not taken into account in the current set up.
