The Nigerian Senate, as the upper chamber of the National Assembly, plays a pivotal role in shaping the nation’s legislative landscape. However, its history is punctuated by instances where members have faced suspensions under controversial circumstances. These suspensions, often arising from allegations of misconduct, breaches of protocol, or clashes of political interests, have not only stirred debates within the legislative chambers but have also resonated profoundly with the Nigerian populace. This article delves into the histories of senators who have been suspended since the inception of the Fourth Republic in 1999, examining the reasons for their suspensions, the justifications provided, court rulings where applicable, and the reactions elicited from Nigerians.
1. Senator Femi Okurounmu (1999)

The dawn of the Fourth Republic saw its first senatorial suspension with Senator Femi Okurounmu, representing Ogun Central. In 1999, Okurounmu alleged that certain senators were conspiring to impeach then-President Olusegun Obasanjo. This claim, perceived as potentially destabilizing, led to his suspension. The Senate deemed his allegations unfounded and damaging to the institution’s integrity, justifying the suspension as a necessary measure to maintain order and discipline within the legislative body. The incident highlighted the fragile nature of Nigeria’s nascent democracy and underscored the Senate’s intolerance for actions that could incite political instability. Public reaction was mixed; while some viewed the suspension as a necessary step to uphold legislative decorum, others perceived it as an infringement on free speech and a senator’s duty to raise pertinent issues.
2. Senator Joseph Waku (2000)

In 2000, Senator Joseph Waku from Benue State was suspended following a highly controversial statement suggesting that a military coup would be preferable to allowing President Obasanjo to continue in office. Waku criticized Obasanjo’s administration, labeling it the worst in Nigeria’s history. These remarks were met with widespread condemnation, leading to his suspension. The Senate justified the suspension on the grounds that Waku’s comments were antithetical to democratic principles and could incite unrest. This action was seen as a reaffirmation of the Senate’s commitment to democracy. Nigerians largely supported the suspension, viewing it as a necessary response to undemocratic sentiments. However, some critics argued that it suppressed freedom of expression.
3. Senator Arthur Nzeribe (2002)

Senator Arthur Nzeribe, representing Imo Orlu constituency, was indefinitely suspended in November 2002 under the Senate presidency of Pius Anyim. The suspension stemmed from allegations of a N22 million fraud and purported anti-senatorial activities. Nzeribe’s controversial political maneuvers, including attempts to impeach the Senate President, further alienated him from his colleagues. The Senate’s decision to suspend him indefinitely was justified as a move to preserve the integrity of the legislative body. The public’s reaction was largely supportive, as many Nigerians were frustrated with corruption and saw the suspension as a stand against unethical behavior. However, some viewed it as politically motivated.
4. Senator Ali Ndume (2017)

In 2017, Senator Ali Ndume, representing Borno South, was suspended for six months after raising allegations against Senate President Bukola Saraki and Senator Dino Melaye. Ndume called for investigations into reports that the Senate was exacting vengeance on Hameed Ali, the former Comptroller-General of the Nigeria Customs Service, due to a seized bulletproof car allegedly owned by Saraki. He also demanded that Melaye be probed for certificate forgery. A Senate panel later cleared both Saraki and Melaye of the allegations, leading to Ndume’s suspension for bringing disrepute to the Senate. The Senate justified the suspension as necessary to maintain the institution’s integrity. Public reaction was divided; some Nigerians saw Ndume’s suspension as an attempt to suppress internal scrutiny, while others believed it was justified to prevent frivolous allegations.
5. Senator Ovie Omo-Agege (2018)

Senator Ovie Omo-Agege, representing Delta Central, was suspended in 2018 after opposing the election reordering bill, alleging it was targeted at President Muhammadu Buhari. Despite apologizing for his comments, Omo-Agege sought legal action to prevent his suspension, which angered his colleagues and led to his eventual suspension for 90 legislative days. The Senate justified the suspension as a disciplinary measure to uphold its rules and procedures. The public’s reaction was mixed; some viewed the suspension as an infringement on a senator’s right to express dissenting opinions, while others saw it as a necessary action to maintain legislative order.
6. Senator Abdul Ningi (2024)

In March 2024, Senator Abdul Ningi, representing Bauchi Central, was suspended for three months after alleging that the 2024 budget was padded by N3 trillion. He claimed that the budget passed by the National Assembly was N25 trillion, while the one being implemented by the presidency was N28.7 trillion. These allegations led to intense debates in the Senate, resulting in his suspension. The Senate justified the suspension by stating that Ningi’s claims were unfounded and damaging to the institution’s integrity. Public reaction was mixed; some Nigerians viewed the suspension as an attempt to suppress whistleblowing, while others believed it was necessary to prevent the spread of misinformation.
7. Senator Natasha Akpoti-Uduaghan (2025)

The most recent suspension occurred in March 2025, when Senator Natasha Akpoti-Uduaghan, representing Kogi Central, was suspended for six months over alleged misconduct. Her suspension followed a protest over the reallocation of her seat in the chamber and public statements that the Senate deemed brought the presiding officer and the institution into disrepute. The Senate’s Committee on Ethics, Code of Conduct, and Public Petitions recommended her suspension, which was subsequently adopted. The Senate justified the suspension as necessary to maintain order and discipline within the legislative body. Public reaction was divided; some Nigerians viewed the suspension as an attempt to suppress a vocal female senator, while others believed it was justified to
