The Ethics and Anti-Corruption Commission has been told to set up offices at county level to help weed out graft in the 47 counties.
Embu Speaker Kariuki Mate said decentralisation of war on graft would scare corrupt public officers at the county level because of constant watch.
Speaking in his office a day after the county was ranked second in the graft index, Mr Mate said it was not enough for EACC to only rank counties but there should be mechanisms to eradicate the vice.
He challenged EACC to bite the bullet and start prosecuting corrupt county governments officials.
Mr Mate claimed that corrupt dealings in county governments were in public domain and prosecution was the only deterrent to future economic crimes.
“When you say that Embu is number two in corruption perception, how many cases in Embu have been taken to court? How many arrests have been taken to court, how many cases are under investigation in Embu?.
“How can we justify and demonstrate that EACC has worked in Embu? Let them go to where corruption is and arrest people, arraign them in court so that we can walk the talk,” he said.
