NASA co-principal and Bungoma Senator Moses Wetangula has been stripped off his Senate Minority Leadership position.
The move is seen as one that threatens to escalate the looming rift in the NASA coalition.
Nasa senators elected their Siaya counterpart James Orengo to the seat in what seemed to be a rebellion against their leaders
On Thursday last week, the Orange Democratic Movement Parliamentary Group meeting at Orange House Passed a resolution to kick out Mr Wetang’ula over claims of mistreating his colleagues in the House.
The speaker was informed of the move but delayed granting ODM its wishes.
Mr Lusaka ruled that even though the party’s meeting that resolved to have the senator replaced was valid, his removal would be suspended as the election of Mr Orengo as his replacement was not procedural.
Boni Khalwale, Ford Kenya deputy party leader, told the party’s National Executive Council meeting in Nairobi that Mr Wetangula can only be removed by the Nasa summit comprising of the four Nasa principals.
