The All Progressives Congress caucus in the Senate on Tuesday sacked Senator Ali Ndume as the Senate Leader.
Senator Ahmad Lawan was however named as replacement.
The decision to sack Ndume was contained in a letter to the Senate by the APC caucus.
Ndume, who was not at plenary when the decision was announced, expressed shock at the development, saying he was not consulted before such decision was reached.
He told newsmen after plenary: “I don’t know whether I have been removed as the Senate Leader.
“This announcement came to me as a surprise.”
As at the time of filing this report, reasons for Ndume’s sack was not known.
