The House of Representatives continues to experience significant shifts in its partisan composition, particularly as the National Assembly primaries approach. In recent weeks, several lawmakers have cited internal leadership crises, divisions, and factionalization within their political parties as reasons for changing party affiliation.
With the defection of sixteen members across party lines over the past two weeks, the total number of defections recorded in the 10th Assembly since June 2024 has risen to 137. These movements span multiple states, including Imo, Kaduna, Kano, Kebbi, Lagos, Niger, Osun, Sokoto, Taraba, Yobe, and Zamfara.
Gains and Losses by Party
The African Democratic Congress (ADC) recorded the highest gains in this latest round, adding eight members, followed by the All Progressives Congress (APC) with five. The Majority Caucus also experienced losses, with three members joining parties within the Minority bloc, reflecting a fluid political landscape.
In terms of losses, the Peoples Democratic Party (PDP) recorded the highest, losing eight seats to other parties. Of these, five members joined the APC, while the ADC and Accord Party gained one and two seats respectively. The New Nigeria Peoples Party (NNPP) recorded the second-highest losses, with four members from Kano State defecting to the ADC.
