The African Democratic Congress (ADC) has congratulated Osun State Governor, Ademola Adeleke, on his victory in the August 15, 2026 governorship election, describing the outcome as a major demonstration of the power of voters and democratic choice.
The opposition Party, however, has raised questions over the Independent National Electoral Commission’s (INEC) handling of its Result Viewing Portal (IReV), demanding an explanation for what it described as a nearly four-hour interruption in the uploading of election results.
The ADC made its position known in a statement issued on Sunday, August 16, by its National Publicity Secretary, Bolaji Abdullahi.
Adeleke, who contested the election on the platform of the Accord Party, emerged victorious in the keenly watched governorship contest, defeating his closest challenger, All Progressives Congress (APC) candidate, Munirudeen Bola Oyebamiji.
The election had attracted significant national attention because of the political stakes surrounding the contest and its potential implications for the 2027 general elections.
The ADC said Adeleke’s victory was particularly significant because of what it described as the enormous political resources mobilised by the APC ahead of the poll.
According to the Party, the outcome showed that access to government structures, political influence and extensive campaign machinery could not automatically translate into victory when voters had already made their choice.
The ADC also commended voters across Osun State for participating in the electoral process despite what it described as intimidation, arrests, violence and a heavy security presence.
The Party said the people of Osun had demonstrated that political power ultimately remained subject to the will of the electorate in a democratic system.
It argued that the result should serve as a message to political parties and officeholders ahead of the 2027 elections, particularly on the limits of using State influence and political structures to determine electoral outcomes.
The ADC alleged that the APC deployed a significant number of political leaders and public officials to Osun during the election period.
It claimed that more than 30 state governors, the President of the Senate, the Speaker of the House of Representatives, federal and state lawmakers, as well as other senior political figures, were involved in the Party’s mobilisation efforts.
The opposition Party described the level of mobilisation as unusually large for a state governorship election.
According to the ADC, the extensive involvement of APC political figures was expected to give the ruling Party a major advantage, but the eventual result showed that voters could still reject the preferred candidate of a politically dominant establishment.
The Party said the Osun election should therefore be seen as an indication that Nigerians could use elections to express their dissatisfaction with Government performance.
It maintained that citizens were not permanently bound to any political party and could change their political choices through the ballot box.
The ADC further argued that the outcome was relevant to the wider political debate ahead of the 2027 general elections.
The Party said Nigerians could peacefully challenge unpopular leadership through elections rather than resorting to violence or extra-constitutional measures.
It described the Osun result as evidence that the electorate could withstand political pressure and make independent decisions at the polling unit.
The Party also criticised the security arrangements surrounding the election, alleging that the scale of deployment and incidents recorded during the exercise could have discouraged voters from participating.
However, it said the situation instead strengthened the determination of many citizens to exercise their franchise.
The ADC’s comments come against the backdrop of concerns that have repeatedly surrounded the use of technology in Nigeria’s electoral process.
INEC has used the Bimodal Voter Accreditation System (BVAS) and IReV as part of efforts to improve transparency and allow members of the public to view polling-unit results electronically. Ahead of the Osun election, INEC had said BVAS would be deployed across the State’s 3,763 polling units, while the system would also facilitate the uploading of results to IReV.
The IReV issue subsequently became a major concern for the ADC.
The Party said it could not celebrate the election result without drawing attention to the period during which result uploads on the portal were suspended.
It demanded that INEC publicly explain what caused the disruption, who authorised it and why the interruption occurred at a sensitive stage of the election when results were being transmitted and collated.
The ADC specifically questioned the circumstances surrounding the suspension and suggested that Nigerians deserved clarity on whether the disruption was caused by a technical problem or another factor.
The Party’s demand reflects wider concerns about electronic result transmission in Nigeria, where IReV has been presented as an important transparency mechanism.
Earlier in 2026, the ADC had criticised attempts to limit electronic transmission of election results, arguing that technology should be used to reduce human interference and strengthen public confidence in elections.
The Party’s latest position therefore places the IReV controversy at the centre of its assessment of the Osun election.
While congratulating Adeleke, the ADC stressed that celebrating the outcome should not mean ignoring issues that could affect confidence in the electoral system.
The Party called on INEC to provide a clear account of the incident and reassure Nigerians that the electronic result-viewing system remains reliable and transparent.
The demand is significant because IReV is designed to give voters, political parties, observers and other stakeholders access to polling-unit results. INEC had previously highlighted the portal as part of the technology being deployed to enhance transparency during elections.
The Osun election was also closely watched because of the political competition between Adeleke and Oyebamiji.
Before the poll, Oyebamiji had repeatedly expressed confidence that the APC would defeat the incumbent Governor, arguing that his Party had built sufficient grassroots support across the State.
The contest also came after months of intense political activity, with observers describing the Osun environment as highly competitive and politically polarised ahead of election day. An EU-backed election observation assessment had earlier warned about political tensions, alleged vote-buying and violence while urging stakeholders to protect the integrity of the electoral process.
For the ADC, Adeleke’s victory has now become more than an outcome in a state-level contest.
The Party sees the result as evidence that voters can still determine electoral outcomes despite the strength of political structures and the influence of incumbency.
It also believes the election could offer lessons for opposition parties preparing for the 2027 general elections.
However, its demand for an explanation from INEC means that its assessment of the poll is not entirely celebratory.
The Party is asking the electoral commission to address the IReV disruption and provide Nigerians with enough information to understand what happened during the period when results were reportedly not being uploaded.
As political parties begin to assess the Osun election, the ADC’s statement has therefore placed two issues side by side: its acceptance of Adeleke’s victory as an expression of voters’ will and its demand for greater transparency from INEC.
The Party’s message is that electoral victory should be respected, but the process through which that victory is recorded and publicly verified must also remain open to scrutiny.
With attention already beginning to shift towards the 2027 elections, the ADC believes the events in Osun provide an opportunity for Nigeria’s electoral institutions to strengthen public confidence, improve transparency and ensure that technology deployed for election management performs effectively when voters and political parties need it most.
