The changes are part of a wider plot that could also see former Head of Public Service and Secretary to the Cabinet Francis Muthaura officially retired.
Muthaura stepped aside last year after the International Criminals’ Court (ICC) confirmed charges against him.
Internal Security PS Francis Kimemia who took over from Muthaura in an acting capacity is set to be confirmed as Head of Public Service.
Acting Permanent Secretaries Mutea Iringo (Internal Security), Gichira Kibaara (Justice), and Prof George Godia (Education) will also be confirmed.
A reliable source at Cabinet office has indicated that the President could also sack some PSs reported by the National Intelligence Service (NIS) as engaging in political campaigns.
“There are increasing concerns that some of these people are soiling the good name of the Government. Civil servants can’t be politicians so they will be pushed out,” said a government insider.
Prime Minister Raila Odinga is particularly under pressure from his ODM brigade to get rid of assistant ministers George Khaniri (Information and Communication), Manyala Keya (Gender), and William Cheptumo (Justice).
Mr Khaniri and Mr Keya have crossed over to the United Democratic Front (UDF) with Deputy Prime Minister Musalia Mudavadi. Cheptumo who has survived three other reshuffles has joined Eldoret North MP William Ruto’s United Republican Party.
Sources at the PM’s office revealed that there is consensus on the sacking of the ministers. Kibaki and Raila who have the powers to act travelled, but are expected to hold talks on the matter on return.
ODM has seven portfolios to fill in the anticipated Cabinet reshuffle, including two ministerial dockets; assistant minister Internal Security left vacant following the death of former Ndhiwa MP Orwa Ojode in a helicopter crash and the resignation of Public Health Minister James Gesami, who is facing corruption charges.
