Human rights lawyer Femi Falana, SAN, has called on the Federal Government to reopen the **MKO Abiola death investigation**, nearly three decades after the presumed winner of Nigeria’s June 12, 1993 presidential election died in government custody. The renewed demand follows continuing disagreement over whether Abiola died solely from existing heart problems or whether his detention and treatment contributed to his death. Nigerians following the controversy should note that claims that he was poisoned have never been established as fact.
Falana made the call while revisiting evidence presented before the Oputa Panel, the commission established by former President Olusegun Obasanjo’s government to investigate abuses committed during Nigeria’s years of military rule.
Abiola died on July 7, 1998, while still being held by the military government led by General Abdulsalami Abubakar. His death came shortly after a meeting with a visiting United States delegation that included senior American officials Susan Rice and Thomas Pickering.
The case remains one of the unresolved issues surrounding Nigeria’s transition from military government to civilian rule and continues to feature in debates about [human rights and democratic accountability](https://newstimes.com.ng/human-rights-ranks-nigeria-fully-authoritarian/).
## Falana raises questions over Abiola’s detention and medical care
Abiola was detained after declaring himself president on June 12, 1994, relying on the result of the presidential election held a year earlier. The election, widely regarded as having been won by Abiola, had been annulled by the military government.
He was arrested under General Sani Abacha’s regime and charged with treasonable felony. He remained in detention for about four years.
Falana argued that Abiola had serious health problems during that period but was not given adequate access to medical treatment.
Concerns about his condition were raised before his death. Archbishop Desmond Tutu, who met Abiola during a visit to Nigeria in April 1998, reportedly expressed concern about his health and called for his release.
Abacha died on June 8, 1998 and was succeeded by Abubakar. Several political detainees were subsequently released, but Abiola remained in custody.
Falana said the circumstances surrounding that continued detention and Abiola’s medical treatment should form part of any fresh inquiry.

Final meeting and disputed cup of tea
Falana also drew attention to testimony presented before the Oputa Panel about the security arrangements during Abiola’s final meeting with the American delegation.
He cited evidence from ACP Theodore Zadok, an officer who had guarded Abiola, and Major A.S. Aliyu, who was then Chief Security Officer to the military Head of State.
According to Falana’s account of the testimony, the normal security arrangements surrounding food and drinks served to Abiola were changed during the meeting. He particularly questioned why Zadok was not at his usual post and raised concerns about tea served during the meeting.
Those circumstances have helped fuel suspicions about Abiola’s death for years. However, suspicion surrounding the tea does **not** establish that it was poisoned or that any member of the American delegation caused his death.
Susan Rice has previously rejected suggestions that she was responsible for Abiola’s death. Accounts of the meeting say Abiola was already showing signs of poor health before he suddenly became seriously ill.
Abdulsalami rejects poisoning allegation
Former Head of State Abdulsalami Abubakar has also rejected claims that Abiola was poisoned.
Revisiting the controversy in 2026, Abubakar said an autopsy involving pathologists from Nigeria, Britain, the United States and Canada concluded that Abiola died from natural causes associated with serious heart disease.
“I do not believe Abiola was poisoned,” Abubakar said, according to reports on his account of the case.
An international autopsy conducted after Abiola’s death similarly reported severe underlying heart disease and said no poison or toxins were detected.
Falana’s argument, however, goes beyond the poisoning allegation. He maintains that questions remain about whether years of detention and inadequate medical care contributed to Abiola’s death.
The Oputa Panel also examined the circumstances and described the death as occurring in “suspicious circumstances”, recommending further investigation.
Why the Abiola case still matters
Abiola’s political legacy remains closely connected to Nigeria’s democratic history. In 2018, the Federal Government moved the country’s Democracy Day from May 29 to June 12 in recognition of the significance of the 1993 election and posthumously awarded Abiola the Grand Commander of the Federal Republic.
His case continues to raise wider questions about state power, political freedom and [democratic rights in Nigeria](https://newstimes.com.ng/nigerias-electoral-amendment-sparks-fierce-debate-over-party-membership-democratic-rights/).
Falana is now asking the government to implement the Oputa Panel’s recommendation by conducting another investigation capable of providing a clearer public account of what happened.
Until such an inquiry produces new evidence, the established position remains that the international autopsy attributed Abiola’s death to heart disease, while questions about the effect of his detention, medical treatment and the circumstances immediately before his death continue to be disputed.
