Nigerian opposition leaders have formed a coalition under the banner of the African Democratic Congress (ADC) to challenge President Bola Tinubu and the ruling All Progressives Congress (APC) in the 2027 general elections. Key figures in the coalition include former Vice President Atiku Abubakar, former Anambra State Governor Peter Obi, former Senate President David Mark, and prominent politicians such as El-Rufai, Rotimi Amaechi, Dino Melaye, Rauf Aregbesola, Aminu Tambuwal, Gabriel Suswan, and Datti Baba-Ahmed. The coalition emerged amid defections from opposition parties to the APC and aims to unify various opposition factions to unseat Tinubu's administration. David Mark and Rauf Aregbesola were appointed as interim leaders to coordinate the coalition's efforts. The ADC, previously a minor party, is now the platform for this alliance, with plans to convert several sitting governors to its fold before the elections. The coalition has faced criticism and skepticism from the APC, which has dismissed it as a group of self-interested politicians, and from some opposition figures who accuse it of internal power struggles and hijacking party structures. The ADC has also accused the Tinubu administration of targeting its leaders in the North East and North West regions to undermine the coalition. Despite challenges, the coalition seeks to capitalize on public dissatisfaction with Tinubu's economic reforms and aims to present a united front against the ruling party. The Peoples Democratic Party (PDP), another major opposition party, has expressed confidence in the coalition's eventual collapse but remains engaged in the political contest. Regional blocs such as the Northern Bloc have adopted the ADC coalition as their platform for the elections. The coalition's formation marks a significant development in Nigeria's political landscape ahead of the 2027 presidential election, highlighting a fierce contest between the ruling APC and a consolidated opposition front.
