The price increase has led to a sharp rise in transport fares and Estonian ride-hailing and food delivery startup Bolt said it had hiked its prices in Nigeria, citing increased operating costs due to higher fuel prices.

Nigeria's fuel subsidy cost the government billions of dollars annually but was popular as it helped keep prices low in Africa's biggest oil producer, which is still grappling with high poverty rates among residents.

The Nigerian Bureau of Statistics says 63% of people living in Nigeria are poor while the World Bank said in a report last year that as many as four in 10 Nigerians live below the national poverty line.

The government said lifting the subsidy - which caused prices to rise to 557 naira per litre from 189 naira at the petrol pumps - will help alleviate a government funding crisis.

But Nigerian Labour Congress (NLC) president Joe Ajaero, after an emergency meeting of the union's executive council in Abuja, said the state oil company NNPC should reverse the price hike.

"The Nigeria Labour Congress decided that if by Wednesday next week that NNPC, a private limited liability company that illegally announced a price regime in the oil sector, refuses to revert itself for negotiations to continue, that the Nigeria Labour Congress and all its affiliates will withdraw their services and commence protests nationwide until this is complied with," Ajaero said.

In 2012, a wave of strikes ensued when Nigeria tried to introduce a similar measure, with authorities eventually reinstating some subsidies. Tinubu, then in the opposition, was among those who opposed ending the subsidies.

On Friday, the president said Nigeria needs to review its minimum wage of 30,000 naira ($65).

"We need to do some arithmetic and soul searching on the minimum wage," he told the ruling party state governors at his offices in Abuja, adding that revenue collection should be strengthened.
