A former Secretary-General of the Nigeria Union of Petroleum and Natural Gas Workers (NUPENG), Frank Kokori is dead.

Kokori died on Thursday in a hospital in Warri, Delta State.

His death was disclosed by his Personal Assistant, Atawada Oke.

Over the past few months, the former NUPENG secretary had been battling a kidney-related ailment.

On November 9, Kokori raised an alarm over his health status from his sick bed.

Twenty-four hours later, Sheriff Oborevwori, Governor of Delta, visited the elder statesman at the hospital and promised that the state would provide support for him to get “high-quality medical treatment”.

Kokori played a significant role in the struggle against the annulment of the June 12, 1993, presidential election.

He mobilised workers against the annulment of the election and the military junta.
