According to a report by American news channel, PBS News Hour, former Petroleum Minister, Diezani Alison-Madueke might have personally supervised the looting of $6 billion (N1.2 trillion) from Nigeria’s coffers.
This was disclosed by the network’s Special Correspondent, Nick Schifrin in a video report published on YouTube on December 2, 2015.
“US and British officials told us Alison-Madueke might have personally overseen the stealing of $6bn (N1.2tr),” Schifrin said in the report which is part of a series titled “Nigeria: Pain and Promise.”
“The most common method is awarding oil contracts to companies owned by friends,” he added.
Edo State Governor, Adams Oshiomhole had made a similar claim after a trip to the US with President Muhammadu Buhari in July but did not name the person involved.
Schifrin also interviewed Emir of Kano, Sanusi Lamido Sanusi who said that the country was losing about $1 billion a month during the Goodluck Jonathan regime.
“In Nigeria, there is no accountability at all and that is why I think Nigeria’s corruption is worse than corruption in most parts of the world. It is the worst type of corruption, it’s stealing,” Sanusi said.
“Frankly, I think a billion dollars under Jonathan a month was about what we were losing,” he added.
Sanusi lost his job as CBN governor after he alleged that $20 billion had gone missing from the coffers of the Nigerian National Petroleum Corporation (NNPC) which was under Alison-Madueke's supervision.
Ms Alison-Madueke was arrested in London on October 2, 2015, on charges of money laundering.
The Emir also said that imprisoning the former petroleum minister would send a message against corruption.
“If she (Diezani) goes to court and is jailed for example, it sends a signal; I think that there is a day of reckoning,” Sanusi said.
Ms Alison Madueke has however denied the allegations of looting levelled against her saying that Sanusi blew the whistle at the time because she didn’t help him to get appointed as the President of the African Development Bank (AfDB).
Kaduna State Governor, Nasir El-Rufai also told the New York Times recently that looting of public funds under Jonathan’s administration took place ‘openly and with records.’
Corruption under Jonathan’s government has been a major subject of discussion in recent times after it was alleged that officials had misappropriated funds meant for Nigeria’s war against Boko Haram.
The discovery was made by a special panel constituted by President Buhari to investigate arms purchases in the country from 2007-2015.
At the fore of the investigations is former National Security Adviser, Sambo Dasuki who is alleged to have supervised the laundering of about $2 billion in funds meant for the procurement of arms.
Dasuki was arrested by the Department of State Services(DSS) on December 1, 2015 and handed over to the Economic and Financial Crimes Commission (EFCC) the day after.
The former NSA is reported to have implicated several prominent persons in the deal including former governors, ex-ministers and members of Jonathan’s party, Peoples Democratic Party(PDP).
Dasuki’s lawyer however denied the report that his client had become an informant.
