Nigerian state oil firm 'withheld $25bn over five years'

Nigeria's state-owned oil company has failed to pay the government $25bn (£17.5bn) over five years, the nation's fiscal commission has said.

It includes $15bn that the nation's auditor general last week said the Nigerian National Petroleum Corporation (NNPC) failed to pay in 2014 alone.
Oil revenue accounts for roughly two-thirds of the government's funding.
President Muhammadu Buhari has promised to crack down on corruption since coming to office last May.
In a statement, the Revenue Mobilization Allocation and Fiscal Commission (RMAFC), an independent body, said: "Records at the Commission's disposal indicate that between January 2011 and December 2015, the total indebtedness of NNPC to the Federation Account was 4.9 trillion naira."
