The Clerk of the House, Mr Paul Bankole, read the separate letters of defection by the lawmakers during the plenary session in Ibadan.
The News Agency of Nigeria reports that the Speaker (Labour Party-Orire), Mrs Wunmi Oladeji ( Labour Party-Ogbomoso North) and Solomon Olukayode (Labour Party-Ogbomoso South) defected to the All Progressives Congress.
Gbenga Oyekola ( Labour Party-Atiba) and Peter Oyetunji (Labour Party-Ogo Oluwa/Surulere), on the other hand, defected to African Democratic Congress and Peoples Democratic Party respectively.
The Minority Leader, Mr Ademola Ige (Accord Party-Ibadan South-East II) and Mr Fatai Adesina (Accord Party-Ibadan South-East I) defected to ADC.
Meanwhile, the house has appealed to the Commissioner of Police in the state, Abiodun Odude, to make conscious efforts to put a stop to gang-related crimes and violence in Oyo town.
The assembly also urged the commissioner to deploy competent police units to tackle the dastardly activities of criminal gangs.
This followed a Matter of Urgent Public Importance raised by Mr Muideen Olagunju (Accord Party-Oyo East/Oyo West) during the plenary.
According to Olagunju, the dramatic upsurge in gang warfare within the town has resulted in residents living in fear.
“The acts of violence are traceable to battle for supremacy among bands of youths in certain black spots within the town.
