Meru Governor Kawira Mwangaza was on Wednesday evening impeached after just 112 days in office.
Kawira Mwangaza has been accused by Members of County Assembly (MCAs) in Meru of nepotism and illegal appointments, among other allegations.
Sixty-seven MCAs voted to impeach the governor. Nkomo MCA Kithinji Ethaiba was absent and was said to be sick.
At the centre of her political problems is her husband, who is allegedly playing a prominent role in the Meru county government.
Mrs Mwangaza has defended her husband Murega Baicu, saying that she had only appointed him to voluntarily roles in her administration.
