The political composition of Nigeria's 10th National Assembly shifted on Monday with the formal defection of Senator Ipalibo Banigo from the Peoples Democratic Party (PDP) to the ruling All Progressives Congress (APC).

Senator Banigo, representing the strategically important Rivers West Senatorial District, has crossed the aisle, a move with immediate numerical consequences. Official tallies now place the PDP's Senate membership at 17, down from 18. This grants the APC an even more commanding majority of 81 senators in the 106-member chamber (three seats are currently vacant).

A Shift in Power Dynamics

This recalibration occurs at a critical legislative juncture. President Bola Tinubu has recently transmitted the 2026 statutory budget of the Federal Capital Territory Administration (FCTA) to the Senate for approval. The APC's strengthened position is expected to streamline the budget's passage, potentially limiting the scope for detailed scrutiny or opposition from a now-diminished PDP bench.

The Bigger Picture: A Weakened Opposition

The reduction to 17 senators marks a new low for the PDP in the current assembly, undermining its capacity for effective legislative oversight or to block executive initiatives. The defection also highlights the ongoing fluidity of political alignments in the Niger Delta region, a key economic zone.

While Senator Banigo's specific reasons for leaving the PDP were not detailed in the announcement, the practical effect is a further consolidation of APC influence in the National Assembly. In a legislature where committee assignments, leadership roles, and agenda-setting are often dictated by party strength, each seat carries significant weight.

The remaining opposition parties—the African Democratic Congress (5), New Nigeria Peoples Party (1), All Progressives Grand Alliance (1), and National Democratic Congress (1)—now hold a combined total of 8 seats, leaving the APC with a dominant super-majority.
