The image of former Minister of Power, Saleh Mamman, being led away in handcuffs after his conviction has become a striking symbol in Nigeria’s long struggle against corruption. For many citizens, it reflects a rare moment where accountability appears to have caught up with a powerful public official.

On May 13, the Federal High Court in Abuja sentenced Mamman to a combined 75 years in prison and ordered him to pay N22 billion in restitution after finding him guilty of fraud and money laundering involving N33.8 billion allocated to key power projects, including the Mambilla and Zungeru hydroelectric schemes. These projects are considered vital to improving Nigeria’s electricity supply and supporting economic development.

The court ruling drew widespread attention due to the scale of the funds involved and the critical sector affected. For years, Nigerians have grappled with persistent power shortages, high electricity costs, and the economic strain caused by an unreliable energy supply, making the diversion of such funds particularly damaging.

The case also attracted public interest following reports that Mamman attempted to avoid serving his sentence. He was said to have left Abuja for Kaduna shortly after the judgment and was later arrested on May 19. Court accounts further suggested he had been hiding in a rented apartment in Rigasa while claiming ill health.

His conviction has reignited wider concerns about accountability among Nigeria’s political elite. Critics argue that many politicians maintain an image of authority and privilege while in office but often resist consequences when faced with legal scrutiny.

Questions have also been raised about Mamman’s reported political ambitions during his trial, including his pursuit of the Taraba State governorship ticket under the ruling APC. Observers say this reflects a broader political culture in which individuals facing serious allegations can still remain active in mainstream politics.

Analysts note that in more stable governance systems, allegations of large-scale corruption are often enough to end political careers. In Nigeria, however, accused officials frequently retain influence, secure political backing, and continue to participate in elective processes.

This trend, critics say, has contributed to public distrust in governance. Corruption is widely blamed for weakening institutions, worsening poverty levels, and slowing national development, particularly in critical sectors such as infrastructure, education, and healthcare.

Nigeria’s standing in global corruption rankings reflects these concerns. In Transparency International’s latest Corruption Perceptions Index, the country ranks 142nd out of 182 nations, scoring 26 out of 100—well below the global average.

Observers also argue that corruption has become deeply embedded in parts of the public sector, with recurring allegations of contract inflation, procurement fraud, ghost projects, and payroll irregularities across ministries and agencies.

Against this backdrop, the Economic and Financial Crimes Commission (EFCC) has been credited with securing Mamman’s conviction, which many see as a significant step in the fight against corruption. The ruling is widely viewed as a signal that public office does not guarantee immunity from prosecution.

The severity of the sentence has also drawn attention, with some noting that given Mamman’s age, the punishment effectively amounts to life imprisonment. Supporters of tougher anti-corruption measures have urged courts to maintain firm sentencing standards in similar cases.

There are growing calls for sustained action against other high-profile corruption cases still in court, including those involving former Central Bank Governor Godwin Emefiele, former Humanitarian Affairs Minister Sadiya Umar Farouq, former Kogi State Governor Yahaya Bello, and former Accountant-General of the Federation Ahmed Idris.

Concerns have also been raised about consistency in anti-corruption enforcement, with critics warning that selective prosecution could weaken public trust. They argue that justice must be applied uniformly, regardless of political affiliation or status.

Experts further stress the need for stronger oversight of Ministries, Departments, and Agencies, many of which have repeatedly been linked to financial irregularities. They maintain that meaningful development will remain difficult unless systemic corruption is addressed.

Several countries, including Singapore, Denmark, Norway, Sweden, the Netherlands, and Germany, are often cited as examples of successful anti-corruption systems built on strict enforcement, transparency, and strong political will.

Nigeria has previously established key anti-corruption institutions such as the Independent Corrupt Practices and Other Related Offences Commission (ICPC) in 2000 and the EFCC in 2003. However, debates continue over how effective these bodies have been in curbing entrenched corruption.

The country’s anti-corruption drive has also faced criticism in the past, including instances where convicted public officials were later pardoned, raising questions about consistency in enforcement and political commitment.

Ultimately, Saleh Mamman’s conviction is being viewed as more than the downfall of a former minister. For many Nigerians, it serves as a broader warning that public office must not be treated as a license for personal enrichment.

Observers say that unless corruption cases are consistently prosecuted and punished without exception, Nigeria’s efforts to curb graft will remain incomplete.
