"It is a gift by the Modi government on the occasion of its first anniversary. More will follow," party spokesman R P N Singh said.
He was reacting to a hike of Rs 3.13 a litre on petrol and Rs 2.71 per litre on diesel from midnight tonight in the second straight steep increase in rates this month.
Modi-led BJP had come to power in May last year, becoming the first national party to secure a majority on its own after 30 years.
