In an election held at the International Conference Centre Abuja Saturday night, Mr. Lawan scored 32 votes, while Akume got 31 to emerge as Deputy Senate president.
Two votes were declared invalid.
The APC has 59 Senators in the 109- member Senate.
Announcing the result, the returning officer of the election, Mala Buni, who is the APC’s national secretary, said by the result, Messrs Lawan and Akume are now the recognised candidates of the APC for the office of Senate president and Deputy respectively.
Senators loyal to another candidate, Bukola Saraki, boycotted the election.
