The event took place immediately after the Senate had taken the prayers, approval of votes and proceedings at plenary in the red chamber in Abuja
The News Agency of Nigeria (NAN) reports that Lawan and Sen. Ovie Omo-Agege were on Tuesday elected by the lawmakers as senate president and deputy senate president respectively.
However, the name of Okorocha, the immediate-past governor of Imo was missing from the senators-elect from the state as a result of the Independent National Electoral Commission (INEC)’s inability to give him a certificate of return.
At Thursday:s plenary, Okorocha took the Oath of Office at the chamber at about 10:39am.
He then advanced to the senate president to have a handshake after signing the necessary documents.
