The African Democratic Congress (ADC) has emerged as the leading minority party in the Senate after several lawmakers defected from their former parties, changing the balance of opposition politics ahead of the 2027 elections.
This shift followed the movement of nine senators into the ADC, reducing the number of seats held by the Peoples Democratic Party (PDP), which previously held the position as the main opposition party in the upper chamber. With the new arrangement, the All Progressives Congress (APC) now holds the majority with 87 senators, while ADC has 9 and PDP has 6. Other parties such as Accord, APGA, NDC, and NNPP each have one seat.
At the same time, the Independent National Electoral Commission (INEC) is preparing to conduct fresh elections to fill three vacant Senate seats in Nasarawa North, Enugu North, and Rivers South East, which became open after the deaths of their representatives.
Lawmakers who defected explained that internal issues within their former parties, including leadership disputes, influenced their decision to move. The changes were not limited to the Senate, as 12 members of the House of Representatives also left their parties for new ones, further reshaping the composition of the National Assembly.
Several members of the House joined the ADC from the Labour Party and other smaller parties, increasing ADC’s presence in the lower chamber from one member to seven. Meanwhile, the APC has grown its numbers in the House to about 268 members, while the PDP has seen a steady drop in its representation over time.
Since the inauguration of the 10th National Assembly in 2023, the PDP has lost a large number of lawmakers across both chambers, while the APC has gained more members. The Labour Party has also recorded a decline, losing all its senators and retaining only a small number of representatives in the House.
Political analysts have reacted differently to the development. Some believe the rise of the ADC could reshape opposition politics if the party is able to manage its internal issues. Others argue that the PDP still remains relevant despite the losses, pointing to its structure and past electoral strength.
Observers also noted that ongoing legal battles and internal disagreements within opposition parties may affect their ability to present strong candidates in the next general election. There are concerns that continued divisions could weaken opposition efforts if not resolved before 2027.
The situation has raised wider questions about the future of opposition politics in Nigeria, with many watching closely to see whether the ADC can maintain its new position or if further changes will alter the current balance again.
