As Nigeria’s opposition leaders converge in Abuja today, the central challenge before them is no longer simply whether they can unite against President Bola Ahmed Tinubu.

It is whether they can make the difficult sacrifices required to turn that unity into an effective electoral strategy.

The April 2026 Ibadan Declaration offered an ambitious blueprint for cooperation among opposition forces. But months later, many of the same political actors remain separated by competing ambitions, preferred candidates and differing calculations about the route to power.

The Abuja opposition gathering therefore comes at a critical moment for the emerging 2027 contest.

Nigeria’s political history suggests that defeating an incumbent requires more than assembling opposition parties under one umbrella.

In Kenya’s 2002 election, an opposition coalition defeated KANU after 39 years in power. But analysts have also pointed to divisions within KANU and widespread public dissatisfaction with economic conditions as important factors in the victory.

Nigeria experienced a similar political shift in 2015.

The APC defeated the PDP after 16 years in power, helped by opposition cooperation, internal divisions within the ruling party and strong mobilisation.

The lesson is straightforward: opposition unity can create an opportunity, but incumbents become vulnerable when their own political foundations begin to weaken and public dissatisfaction grows.

That reality places a significant burden on Nigeria’s opposition ahead of 2027.

President Tinubu’s administration faces widespread concerns over poverty, food prices and the cost of living. Yet the forces seeking to replace him remain divided over how best to convert those concerns into electoral support.

The opposition landscape currently features several prominent political figures with presidential ambitions.

Former Vice-President Atiku Abubakar is now seeking the presidency under the African Democratic Congress, ADC, with former Rivers State governor Rotimi Amaechi as his running mate.

Peter Obi remains a major figure within the Obidient movement and is associated with the emerging Nigeria Democratic Congress, NDC, alongside Rabiu Musa Kwankwaso.

Oyo State Governor Seyi Makinde has also entered the wider opposition conversation.

Each political figure brings supporters, structures and political resources. The problem is that a coalition presidential contest cannot accommodate every ambition.

At some point, one candidate may have to withdraw in favour of another.

That is precisely where previous efforts at opposition consolidation have encountered difficulty.

The question that remains unanswered is simple but politically explosive: who steps aside for whom?

Any opposition strategy must also account for the strength of the incumbent.

The APC controls the federal government and possesses extensive political structures across the country. Tinubu also enjoys the institutional advantages that accompany the presidency.

The ruling party has significant representation within the National Assembly, while concerns about the independence and credibility of key state institutions continue to feature prominently in political debates.

The Independent National Electoral Commission, INEC, also faces a credibility challenge, with sections of the electorate expressing distrust over election administration and announced results.

These factors make the opposition’s task considerably more complicated.

Winning the presidency will require not merely popularity, but an organisation capable of mobilising voters, protecting votes and sustaining a nationwide campaign.

The G100 summit scheduled for Abuja is not expected to produce an immediate decision on a single presidential candidate.

Rather, its stated objective is to establish a structure through which questions surrounding candidacy and cooperation can be negotiated collectively.

That approach may help keep the various camps at the table.

But eventually, the opposition will have to confront the issue that has repeatedly threatened its unity: presidential ambition.

The NDC has already presented Peter Obi as its strongest and most popular opposition candidate.

Supporters of Atiku are unlikely to accept that assessment without a contest. And other political actors also have their own calculations.

The challenge is therefore not simply creating a coalition. It is deciding who leads it.

Another sensitive issue confronting the opposition is Nigeria’s longstanding debate over political power between the North and South.

Although the Constitution does not establish a formal rotational presidency, political parties have historically used zoning and regional balancing as tools for managing competition.

The PDP’s decision in 2002 to support continued southern leadership before power would return northward was one prominent example.

Olusegun Obasanjo secured a second term in 2003 before Umaru Musa Yar’Adua eventually emerged as the PDP’s presidential candidate in 2007.

Yar’Adua’s death in office altered that arrangement, with Goodluck Jonathan completing the term and subsequently winning the 2011 election.

The eight-year expectation was therefore disrupted.

Muhammadu Buhari later completed two terms in office, returning power to the South with Tinubu’s victory in 2023.

Tinubu has now completed his first four-year term and is seeking another. That creates another political calculation for the opposition.

A section of southern Nigeria may view another southern presidency as a continuation of the region’s expected eight-year cycle, while northern votes remain indispensable to any candidate seeking to win the presidency.

The eventual opposition candidate will therefore have to balance regional sentiment with electoral mathematics.

The deeper problem may not be ideology. It may be ego.

Political leaders often speak about national interest while simultaneously protecting their own political calculations.

Yet a successful coalition requires individual actors to surrender something for the larger objective.

That is the principle captured by the African philosophy of Ubuntu: “I am because we are.”

For Nigeria’s opposition, the concept has practical political meaning.

A candidate may be popular but still need to compromise.

A party may have structures but lack sufficient national reach.

A political heavyweight may command resources but not possess the broadest coalition.

The strongest opposition arrangement may therefore not be the one that produces the most powerful individual candidate, but the one capable of combining regional reach, voter enthusiasm, political structures and organisational discipline.

The Abuja gathering is consequently about more than another political meeting.

It is part of a larger contest over who will define Nigeria’s political alternative before voters even reach the ballot box.

If the opposition allows the perception of fragmentation to persist, the APC could benefit from the psychological advantage of appearing inevitable.

But if opposition leaders can agree on a credible candidate, develop a compelling national programme and build a mechanism for protecting votes, the political equation could change considerably.

History shows that dominant parties can lose. It also shows that opposition parties can squander opportunities.

The 2015 election demonstrated what coordinated opposition can achieve. Earlier experiences have equally demonstrated how internal rivalries can undermine political alliances.

The opposition therefore faces a choice.

It can continue presenting individual ambitions as competing claims to national rescue. Or it can decide that defeating the incumbent requires some of those ambitions to be sacrificed.

The ballots will ultimately determine the winner in 2027.

But before Nigerians make that choice, the opposition leaders meeting in Abuja must make theirs.

The real question is not whether they can defeat Tinubu. It is whether they can first defeat the divisions within themselves.
