The Director-General of the World Trade Organisation, Ngozi Okonjo-Iweala, has recounted how a probe into an alleged $2.4bn fuel subsidy fraud led to threats against her and the kidnapping of her mother.

Okonjo-Iweala said the abductors demanded that she resign as finance minister and leave the country in exchange for her mother’s release.

She spoke about the ordeal during an interview with Bloomberg’s Francine Lacqua on the Leaders programme, published earlier this week.

According to her, the investigation began after officials noticed a sharp rise in claims submitted by fuel importers under Nigeria’s subsidy programme.

She said, at the time, Nigeria relied on imported refined petroleum products to meet domestic demand, despite being an oil-producing country. Under the subsidy arrangement, importers received government payments that allowed them to sell petrol at regulated prices, but the amounts being claimed had risen to levels that raised suspicion.

“So I went to the president and said, look, something is going on here. Could we audit the accounts? And he said, yes, go ahead. And we found about $2.4 billion worth of fraud. So we refused to pay,” she said.

She said the decision prompted threats against her, before her mother was abducted.

“I was told that for her to be released, I should resign and leave the country,” she said.

Okonjo-Iweala described the five-day ordeal as one of the most painful periods of her life, saying she feared her actions could lead to her mother’s death.

“It was a terrible, terrible five-day ordeal. I think the worst in my life,” she said.

Her mother was held in a forest before escaping one night, she said.

“She was held in the middle of a forest, and one night she escaped. She’s still alive. She’s 96 now,” she said, adding that her mother still becomes distressed whenever the incident is mentioned.

Asked whether she had considered quitting during the crisis, Okonjo-Iweala said she would have put her mother’s life ahead of remaining in office.

“Between my mother, having my mother alive and staying in a job, I would pick my mother any day,” she said.

However, she recalled that her father urged her not to give in to the kidnappers’ demands.

“He said, we don’t give in to blackmail. And he said, you’ve got to carry on. You’ve got to go to work,” she recounted.

Okonjo-Iweala said she initially felt paralysed by fear and considered resigning to secure her mother’s release. She added that the experience left her with a sense of guilt that she still carries.

“I never dreamt my parents could ever be touched in this way, that people would be that evil,” she said.

She said her experiences over the years had made her more patient and helped her focus on finding solutions when faced with difficult situations.

“I feel that this is a real fight that has to be waged. If you are a country that is not that rich, every single penny counts,” she said.

Okonjo-Iweala served as Nigeria’s finance minister under former President Goodluck Jonathan before becoming WTO director-general in March 2021.

Her mother, Kamene Okonjo, was kidnapped from her home in Ogwashi-Uku, Delta State, in December 2012. The incident drew national attention amid concerns about the safety of the finance minister’s family.
