New Delhi, Dec 03 (ANI): Petroleum minister Dharmendra Pradhan on Wednesday said that the government hiked excise duty on petrol and diesel for the second time in three weeks to shore up revenue to meet budget deficit without burdening the consumer. The government had on Tuesday raised excise duty on petrol by Rs.2.25 per litre and by Rs.1 a litre on diesel but retail pump rates will not be increased as oil firms decided to absorb the duty change for the time being.
