Mr Iroju Ogundeji Tuesday was impeached as the Deputy Speaker of the Ondo State House of Assemby.
Ogundeji was impeached during the plenary session of the Assembly on Tuesday.
He was removed after 18 out of 26 lawmakers signed for his removal and the signatures were received by the Speaker of the House, Bamidele Oloyeloogun, during the session.
Ogundeji was among the 18 lawmakers who defected to the ruling party from the Peoples Democratic Party, PDP, shortly after Governor Rotimi Akeredolu took over the power in the state in February 2017.
Following the impeachment, he was immediately replaced by Bimbo Fajolu, who represents Ile Oluji /Oke Igbo state constituency.
