Senate President Ahmed Lawan has swore-in Senator Smart Adeyemi of the All Progressives Congress (APC).
Adeyemi was declared the winner of the just-concluded rerun in the constituency by the Independent National Electoral Commission.
The swearing-in was done by the Clerk of the Senate, Nelson Ayewoh, at the start of plenary.
The fact of his swearing-in was shared on the verified Twitter handle of the Senate on Wednesday morning.
Adeyemi is returning to the Senate about five years after he lost the seat to Melaye at the 2015 election.
