Nigeria oil firm overpaid Goodluck Jonathan's government

An audit has found that Nigeria's state oil company overpaid the government $750m (£490m), but also found it had not properly accounted for $1.48bn.

The financial report follows allegations in 2013 by then-central bank chief Lamido Sanusi that the firm had failed to account for about $20bn.
It caused a huge uproar in Nigeria, forcing President Goodluck Jonathan to order an independent audit.
His office released the findings as he prepares to step down in a month.
