Nairobi Governor Mike Sonko is expected to appear before the Senate Standing Committee on Devolution and Intergovernmental Relations on Wednesday this week over the composition of the County Executive.
The committee will be seeking an explanation on why Governor Sonko has been operating without a deputy governor for almost one and a half years now.
He will also be required to shed more light on why the county has also been operating without a number of County Executive Committee Members, after previous holders of the positions either resigned or were sent home.
The most recent to resign was Nairobi County Education minister Janet Muthoni-Ouko who quit in January this year.
The Nairobi Governor was expected to appear before the Senate Committee last week but was out of the country.
He was invited before the committee after Nairobi Senator Johnson Sakaja requested for a statement on the proper constitution of the Nairobi County Government.
