Members of the County Assembly have criticised the Senate for "usurping" their powers by summoning Governor Mike Sonko to explain why he has not appointed a deputy governor 15 months after Polycarp Igathe resigned.

Majority Leader Abdi Guyo said that lack of a deputy had not hampered county operations, adding that Mr Sonko had already nominated four women candidates and all that remained was to table their names in the county assembly.

The Senate Committee on Devolution and Intergovernmental Relations wants to know why Sonko ignored a court directive that nominations for DG should be done in 14 days if a vacancy arises.
