President Muhammadu Buhari, who has not said whether he will seek a second term in elections next February, came to power in 2015 vowing to improve the lives of ordinary Nigerians.
But the IMF recently said the people were getting poorer.
Public outrage over the gap between rich and poor could become an election campaign issue in the coming months.
Usman Mohammed, a civil servant in Abuja, said the money allocated for lawmakers’ expenses was “outrageous”.
“They are supposed not to earn up to that amount of money when people hardly survive,” he said.
A man selling wallets to drivers stuck in traffic on the gridlocked streets of the commercial capital Lagos, who gave his name only as Chijioke, said Nigeria’s leaders were failing their people.
“Our leaders will not think about us. We are hustling not because we like it but we have to help ourselves,” he said.
Chijioke makes around 800 naira – just $2.22 – a day by weaving between cars under the equatorial sun for several hours each day.
Africa’s largest economy is only slowly emerging from recession. Inflation, despite slowing down for 13 months in a row, remained in double figures at 14.3 percent in February.
Food inflation, which hovered around 20 percent throughout last year, stood at 17.6 percent last month.
The expense figures discussed by Sani, a member of Buhari’s All Progressives Congress party with a reputation for being a firebrand politician, had not previously been disclosed.
“When that light of transparency is cast on all these personalities and offices, then Nigerians will come to know whether it is worth their while to support or sustain the big government as we have now,” said Sani.
