Nigeria's Opposition Alliance Crumbles as Leading Figures Exit, Undermining Unity Ahead of 2027 Election

On May 5 2026, former presidential candidates Peter Obi and Rabiu Kwankwaso announced they were leaving the African Democratic Congress (ADC)-led opposition coalition that aimed to field a single candidate against President Bola Tinubu in the January 2027 election, citing numerous legal disputes and internal divisions.

Announced on April 25 2026 under the “Ibadan Declaration,” the coalition united the ADC, former vice-president Atiku Abubakar, and regional politicians including Obi and Kwankwaso. It aimed to overcome the fragmented opposition that secured roughly 60 % of the 2023 vote, while Tinubu won with about 35 %. The grouping was described as the most ambitious opposition realignment in more than a decade.

Obi said his departure was driven by numerous legal disputes and internal divisions. ADC spokesperson Bolaji Abdullahi announced that the Ibadan Declaration would be reviewed. Presidency spokesperson Bayo Onanuga dismissed Obi as opportunistic and questioned his political credibility. SBM Intelligence partner Cheta Nwanze warned that the alliance appears to be on the brink of collapse.

Analyst Cheta Nwanze warned that the division could cause the opposition to eat into its own support. Onanuga criticized Obi’s tactics as opportunistic, suggesting they could lead to defeat. The comments underscore internal dissent over the coalition’s viability.

Without Obi and Kwankwaso, the coalition’s ability to merge the opposition’s 60 % base is weakened, raising the likelihood of vote-splitting that could preserve Tinubu’s advantage. Analysts warn that the fractured opposition could eat into its own support. The split also reflects Nigeria’s deep religious and ethnic cleavages, which have historically shaped party alignments and could further complicate coalition building.

• “endless court cases, internal battles, suspicion, and division” — Peter Obi, former presidential candidate

• “Under the present circumstances that we find ourselves in, the Ibadan Declaration, which canvassed a single presidential candidate from these willing participating parties, will have to be reviewed,” — Bolaji Abdullahi, ADC spokesperson

• “The political nomad is on the move again. Ignore all those puerile reasons he gave in these illogical musings, a self-serving letter to his mob. Peter Obi is a politician made of jelly, an opportunistic fellow. He can't fight Atiku or Amaechi for the ticket of ADC. He pursues the easy road, that will only lead him to doom, like in 2023,” — Bayo Onanuga, presidency spokesperson

• “The feared scenario has materialised: a fractured opposition that will cannibalise its own votes,” — Cheta Nwanze, SBM Intelligence partner

The January 2027 presidential election will proceed with the opposition still seeking a unified candidate. Observers expect further realignments, while Tinubu’s campaign may exploit the disarray.
