Bobasi Member of Parliament Innocent Obiri now wants the constituency to be split into two.
The lawmaker argues that the constituency is big with a higher population compared to the other constituencies in Kisii County.
"Bobasi constituency is the biggest in the county and there is need of splitting it into two. The Constituency Development Funds that I receive cannot run the whole constituency," he said.
Mr Obiri said that the electoral agency IEBC should move with speed and review the boundaries of the constituency.
He said the reason the constituency was lagging behind in terms of development was that it was huge in size.
"Students in this constituency have not seen the benefits of CDF because of its huge size," he said.
He said that if the constituency will not be split into two then the Government should increase funds it sends to the constituency.
He was speaking at Nyagiki Seventh Day Adventist (SDA) on Saturday during a fundraiser.
