West Pokot has passed the Constitution of Kenya (Amendment), Bill 2020.
The county assembly now becomes the first in the Rift Valley region, to pass the Bill paving way for the BBI referendum.
Nationally, West Pokot becomes the fifth county to pass the bill after Busia, Siaya, Kisumu and Homa Bay county assemblies.
Only Baringo County has so far rejected the Bill during a chaotic session last week.
