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, Governor Nasir El-Rufai, Rotimi Amaechi, Dino Melaye, Rauf Aregbesola, Aminu Tambuwal, Gabriel Suswan, and Datti Baba-Ahmed. David Mark and Rauf Aregbesola were appointed as interim leaders to coordinate the coalition's campaign. The coalition aims to unify opposition parties and convert ADC from a minor party into a major political force to unseat Tinubu's administration, which has faced criticism over economic reforms and governance. The APC has dismissed the coalition as a gathering of self-interested politicians and predicted its defeat in 2027. The coalition has faced internal and external challenges, including criticism from other opposition groups like the African Action Congress and Labour Party factions. Despite this, the ADC coalition is actively recruiting sitting governors and has mobilized legal support for ongoing court cases. The coalition's formation coincided with local government elections in Lagos State, which were marked by logistical issues, low voter turnout, allegations of irregularities, and security measures. Governor Babajide Sanwo-Olu of Lagos and other officials participated in the elections amid these challenges. The Tinubu administration has accused opponents of plotting to overthrow the government, while the coalition accuses the administration of targeting its leaders to undermine their efforts. The opposition coalition emphasizes its democratic mission to rescue Nigeria from poverty, corruption, and ineffective governance under the APC-led government.
