The motion was tabled before the house by minority whip and Makongeni MCA Peter Imwatok on Thursday, February 20.
The ward representatives cited gross violation of the Constitution, County Government Act, Public Procurement and Disposal Act as well as the Public Finance Management Act.
The gold-loving county boss was accused of having influenced the award of lucrative tenders to companies associated with his immediate family and close relatives.
In the petition, the governor who is well known for impromptu raps was also accused of hiring casuals without involving the county public service board.
While tabling the motion, Imwatok told the house that the governor had failed to account for county resources and caused unsustainable debts as well as pending bills.
“These pending obligations were never disclosed in the county fiscal strategy paper 2018. The governor failed to implement the medium term debt management strategy for the financial year 2018-2019 placing the county in precarious financial position,” the MCA said.
Imwatok also said that the governor has disregarded the county assembly as an arm of the county government by diverting funds meant for the entity to other projects.
The ward representatives further sought to remove the governor for illegally and unlawfully receiving kickbacks in the new Dandora stadium.
Speaker Beatrice Elachi acknowledged reception of the impeachment motion and is expected to give way forward on when they will debate on the matter.
The County Governments Act stipulates that if the allegations are not substantiated, there will be no further debating.
Should the majority of MCAs vote for impeachment of Sonko, the governor shall cease to hold office and if saved, the county boss can’t be removed on similar charges for three months after the vote.
