The Head of Public Service, Felix Koskei, has directed Cabinet Secretaries to retain only one advisor each, reducing the number from two.
He stated that the advisors' names to be retained must be submitted by Thursday, July 11.
In a circular dated July 8 to all Cabinet Secretaries, Koskei noted that the move is part of a broader strategy announced by President William Ruto on July 5.
Ruto outlined austerity measures and state interventions to enhance government efficiency and effectiveness during the address.
"The sacrifices made by taxpayers must be matched by fiscal discipline in the public service,” said Koskei.
He added that the measures aim to restore faith in public institutions by enhancing accountability and transparency.
Personal staff for Cabinet Secretaries will remain as set out in the Public Service Commission guidelines, which allow for two staffers.
"Assess your office's requirements and indicate the advisor you wish to retain to support your portfolio mandate. Advisors beyond the set threshold will be phased out from the Public Service,” Koskei added.
The directive stipulates that the number of advisors in government will be reduced by 50 per cent, effective immediately.
Cabinet Secretaries must submit advisors' names to be retained to the Public Service Commission, with a copy to the Head of Public Service, by the close of business on July 11.
