A Lagos Special Offences Court in Ikeja has sentenced Mamman Ali, son of former Peoples Democratic Party (PDP) chairman Ahmadu Ali, to 14 years in prison for his role in a ₦2.2 billion oil subsidy fraud.

Also convicted was oil marketer Christian Taylor, Ali’s co-defendant. The duo were found guilty on multiple counts, including conspiracy to obtain money by false pretences, forgery, and use of false documents. The charges were filed by the Economic and Financial Crimes Commission (EFCC) under the Advance Fee Fraud Act and the Criminal Law of Lagos State.

Justice Mojisola Dada, delivering judgment on Tuesday, said the prosecution “established its case beyond reasonable doubt,” describing the actions of the defendants as “a serious breach of public trust.”

According to EFCC prosecutor Seiduh Atteh, the pair fraudulently claimed they had imported over 20 million litres of petrol through Nasaman Oil Services Ltd, thereby receiving ₦1.48 billion from the Petroleum Support Fund.

The court found the importation claim to be entirely fabricated.The case, initially handled by Justice Adeniyi Onigbanjo, was later reassigned to Dada after Onigbanjo recused himself. The EFCC presented documents and witness testimonies during the re-arraignment, which formed the basis of the conviction.

Despite initially pleading not guilty to a 49-count charge—later amended to 57—the defendants were convicted on several counts.This high-profile sentencing marks another major win for the EFCC in its anti-corruption drive targeting subsidy fraud in Nigeria’s oil sector.
