Former Deputy Senate President, Ovie Omo-Agege, has resigned from the All Progressives Congress (APC) and is expected to announce his membership of the National Democratic Congress (NDC).
A source close to the former Delta Central senator confirmed the development on Wednesday to The Whistler, saying Omo-Agege submitted his resignation on May 22 before making his exit public.
“He has left APC. He will announce NDC soon,” the source said.
“You can call it an earthquake because Omo-Agege was one of APC’s biggest political figures in Delta.”
According to the source, supporters and loyalists of the former senator are expected to move with him to the NDC.
In his resignation letter addressed to the APC chairman in Orogun Ward 2, Orogun, Ughelli North Local Government Area, Omo-Agege said his political objectives were no longer aligned with the party.
“It is clear my political objectives and those of my constituents are better served outside the APC,” he wrote.
He added, “I will not remain a sitting duck in a party where I cannot advance the interests of Delta Central, Delta State and Nigeria.”
PrimeTimes Nigeria reports that Omo-Agege’s resignation came 10 days after he lost the APC Delta Central senatorial primary to Senator Ede Dafinone.
In the primary held on May 17, Omo-Agege polled 3,643 votes, while Dafinone scored 116,252 votes to secure the party’s ticket for a second term.
His planned move to the NDC follows recent defections by former Labour Party presidential candidate Peter Obi and former Kano State Governor Rabiu Kwankwaso from the African Democratic Congress (ADC).
Both politicians joined the NDC earlier in May, citing the need to rescue Nigeria from worsening insecurity and economic hardship.
Since then, the party has continued to attract interest from federal lawmakers and opposition figures across the country.
An NDC chieftain in Delta State, James Onosakponome, had recently urged Omo-Agege to join the party and contest the 2027 governorship election instead of returning to the Senate.
Onosakponome argued that a Senate return would amount to a political demotion for a former deputy senate president.
The development also comes amid reports that a Federal High Court in Abuja nullified parts of INEC’s 2027 election timetable, opening a window for aggrieved aspirants who lost primaries to switch parties.
INEC has since appealed the judgment.
