Kibwana said Makueni people have expressed their intention to support ODM Raila Odinga’s Azimio la Umoja.
“…and will not be hoodwinked by people seeking self-aggrandizement. While I respect Adelina for the good working relations for the last nine years, her latest move puts our working together on the edge,” he said.
“The voice of the people of Makueni has always been our guide in decision making. I will not abandon that principle for political expediency. Adelina will walk alone.”
She has been holding meetings with different groups of people across the county as she seeks support for her bid to become the county’s next woman representative.
Mwau has been Governor Kivutha Kibwana’s deputy since 2013.
