President Muhammadu Buhari, elected a year ago on an anti-corruption ticket and who has said he believes officials have stolen around $150 billion from the public purse in the past decade, ordered all state accounts to be merged into one last August.
Every ministry and state body now pays its revenues into the account, held at the central bank and known as the Treasury Single Account (TSA). Previously, ministries and agencies operated more than 10,000 bank accounts with commercial lenders, officials said.
