Nine senators dumped the PDP for the African Democratic Congress (ADC), citing the protracted leadership crisis that has polarised the platform.
The defections has catapulted the ADC as the most dominant opposition party in the Senate.
The ADC now has 9 senators, PDP down to six, APGA 1, Accord1, NNPP 1, NNDC 1, SDP 0, LP 0, with three seats vacant.
The ADC has an overwhelming majority of his seven senators.
The defectors, whose letters of defections were read by Senate President Godswill Akpabio during plenary, are Aminu Waziri Tambuwal (PDP – Sokoto South), Binos Dauda Yaroe (PDP – Adamawa South), Lawal Adamu Usman (PDP – Kaduna Central), Mohammed Ogoshi Onawo (PDP – Nasarawa South), and Augustine Akobundu (PDP – Abia Central).
There was mild drama over the defections of LP Senators Victor Umeh (Anambra Central), Tony Nwoye (Anambra North) and Ireti Kingibe (FCT) to the ADC which sparked a constitutional debate because senators said their no more division in the LP.
Also, APGA Senator Enyinnaya Abaribe (Abia South) left for ADC, Senator Seriake Dickson (Bayelsa) moved from PDP to Nigeria Democratic Congress (NDC) and Deputy Minority Leader Lere Oyewumi (Osun West) moved to the Accord Party.
