The pump price of Premium Motor Spirit, popularly called petrol, was raised from N537/litre to N617/litre at some filling stations operated by the Nigerian National Petroleum Company Limited in Abuja on Tuesday. Independent oil marketers confirmed the increase in the cost of the commodity, as they stated that any shift in price by NNPCL stations was an indication of a rise in the pump price of PMS. “This is because NNPCL is still the major importer of petrol into Nigeria currently, though other marketers are gradually importing the commodity. The price this (Tuesday) morning at some NNPCL stations is N617/litre,”
