How Bola Tinubu and Rauf Aregbesola went from political blood allies to open enemies — and why the fracture now threatens the old order in southwest politics. Once among the most formidable alliances in Nigerian politics, Bola Tinubu and Rauf Aregbesola are now locked in open confrontation. This Sunday explainer traces the feud from succession battles and party structure to defection, discipline and full political rupture.

LONDON —
There are quarrels in politics. Then there are implosions.
The Tinubu-Aregbesola rupture belongs in the second class. In the past weeks, the old bitterness burst again into public view when Aregbesola, now serving as a top official in the ADC, described President Tinubu’s “Renewed Hope” agenda as “a scam” at the party’s convention. The presidency responded with undisguised contempt, saying the agenda was not a scam and attacking Aregbesola’s own record in office. By then, the language of reconciliation had vanished. What remained was the language of political war.
That is what makes this story so consequential. Aregbesola was never a distant associate of Tinubu’s political empire. He was part of its core history. He served as commissioner for works in Tinubu’s Lagos administration, became governor of Osun after a long electoral and legal struggle, and later served as minister of interior. For years, he was widely seen as one of the most visible products of Tinubu’s political machine. Their relationship was not an ordinary alliance of convenience. It was one of the defining mentor-protégé arrangements in southwest politics.
What went wrong was not a single argument. It was a slow collapse. The evidence in the public record points to four pressure points: control of party structure, the Osun succession battle, presidential loyalty, and the final humiliation of defection into an anti-APC coalition.
The First Crack: Control of the Machine
The first clear public sign of trouble surfaced in 2020. Reports indicated that Aregbesola revamped the Mandate Group, a powerful Tinubu-aligned caucus in Lagos, without Tinubu’s approval and inserted figures he trusted. That mattered because this was not a social club. It was part of the architecture of influence. In machine politics, reorganising a core caucus without the blessing of the principal is not housekeeping. It is a declaration.
Even though both camps publicly downplayed the rift at the time, the move exposed a problem that would only grow larger: Aregbesola no longer seemed content merely to operate within Tinubu’s structure; he appeared increasingly willing to reshape part of it.
This was the moment the loyal Lieutenant began to look less like an heir-in-waiting and more like a rival with his own base.
The Osun Wound
But the emotional centre of the fallout was not Lagos. It was Osun.
Accounts of the dispute repeatedly point to the rise of Gboyega Oyetola as a turning point. Public reporting in 2022 said the “seed of conflict” was planted when Tinubu allegedly imposed Oyetola on Aregbesola as chief of staff. Whether one treats that as a settled fact or as the account of insiders, the larger point is clear: Oyetola’s ascent became the hinge of the quarrel.
In Nigerian politics, a chief of staff is rarely just an administrator. He can become the preferred successor. And once succession enters the room, sentiment often leaves.
The real issue was inheritance. Aregbesola seems to have regarded Osun as a political house he had fought to build and lead. Tinubu, as the broader architect of the Southwest Machine, remained the ultimate authority above the house. Once those two claims collided, the old alliance began to rot from within.
Rebellion in the Open
By the build-up to the 2022 Osun governorship primary, the quarrel was no longer a rumour. It was a rupture. Aregbesola backed Moshood Adeoti against Oyetola. That was not routine dissent. It was an open revolt against the succession order associated with the dominant APC establishment in the state.
That was the moment private bitterness became public insurrection. A protégé was no longer managing grievances behind closed doors. He was sponsoring resistance against the succession line preferred by the wider power structure. Once that happened, the quarrel ceased to be interpersonal. It became a fight over legitimacy.
The feud stopped being a family quarrel the moment Aregbesola backed an alternative future for Osun.
The Defeat That Hardened Everything
Then came the loss that made compromise harder. Osun APC went into the July 2022 governorship election carrying internal fractures that were already widely reported. Oyetola eventually lost. That defeat mattered because losses in politics do what arguments alone cannot do: they assign blame.
After Osun slipped, every side had a grievance that could be sharpened into an accusation. Tinubu’s camp could see Aregbesola as a destabiliser. Aregbesola’s camp could see itself as sidelined, disrespected and then scapegoated.
That is why the Osun election was more than an electoral loss. It was the event that converted resentment into something closer to permanent estrangement.
The Unforgivable Step
If Osun made the conflict dangerous, the presidential season made it unforgivable. Reports later indicated that the relationship worsened when Aregbesola openly supported Yemi Osinbajo’s presidential ambition against Tinubu’s.
In elite politics, that is not a minor breach. A local disagreement can sometimes be absorbed. Presidential divergence at the decisive hour is much harder to pardon. It signals that the old contract of loyalty has broken at the highest possible level.
From there, the break became institutional. In late 2024, the Osun APC suspended Aregbesola over alleged anti-party activities. In January 2025, the Omoluabi Progressives, a group aligned with Aregbesola, quit the APC, citing ostracism, suspension, and expulsion of members. Days later, the split was no longer merely political folklore; it had become formal party discipline and separation.
The Final Crossing
The last line was crossed in July 2025, when Aregbesola accepted appointment as ADC national secretary after the opposition coalition adopted the party as a platform for 2027. At that point, Tinubu’s former lieutenant was not merely estranged. He had attached himself to an organised alternative.
The symbolism was devastating: a man built within the old machine had stepped into a coalition seeking to challenge the ruling order itself.
So when Aregbesola now attacks “Renewed Hope” as a scam, he is doing more than criticising policy. He is repudiating the political order that once elevated him. And when the presidency answers by invoking his record and old dependence, it is doing more than rebutting an opposition line. It is a litigating betrayal.
What died here was not simply friendship. What died was an arrangement about power, obedience and inheritance.
What Really Went Wrong
The cleanest answer is this: Aregbesola stopped behaving like a permanent political son, and Tinubu’s system was never designed to celebrate that kind of independence.
Tinubu’s politics have long depended on hierarchy, structure and managed succession. After years of service and political investment, it appears to have reached the point where subordination is no longer acceptable. Once he began asserting a stronger claim over political inheritance, especially in Osun, rupture became increasingly likely.
That is why this feud matters beyond the two men at its centre. It offers a case study in how Nigerian power blocs rise and fracture: shared struggle, joint victory, expansion, then succession — and, at succession, the old harmony collapses. The protégé asks whether he is an heir or a steward. The principal asks whether he is being repaid with loyalty or rebellion. After that, every appointment becomes a provocation and every election a referendum on obedience.
In the end, the Tinubu-Aregbesola breakdown was not caused by one speech or one meeting. It was produced by the oldest and most dangerous question in machine politics: who owns the structure after the structure has won power?
Tinubu and Aregbesola answered that question differently. That is why the brotherhood collapsed. And that is why the war is still not over.
