Row over Nigeria budgetpublished at 12:30
Nigeria's parliament has postponed voting on the 2016 budget from 25 February after a dispute between ministers and senior civil servants over spending plans.
President Muhammadu Buhari presented a record $30bn (£20bn) budget in December but asked for it to be withdrawn in January to make changes after a further fall in oil prices.
MPs said they have witnessed disagreements between various ministers and top civil servants.
"We don't want to pass a budget that will be returned to us. We need to remove all ambiguities and paddings," said Danjuma Goje, the chairman of the budget committee in the Senate, Reuters news agency reports.
On Monday, Health Minister Isaac Adewole accused some civil servants of changing his ministry's allocation.
Nigeria, Africa's biggest largest economy and oil producer, has held talks with the World Bank and African Development Bank and China Exim Bank with the hope of raising some money to fund the budget deficit.
