The government on Friday cut the petrol price by Rs4 per litre and kept the diesel rate unchanged with immediate effect for the week ending June 12, owing to changes in global prices over the past week. Accordingly, the ex-depot price of high-speed diesel (HSD) will remain fixed at Rs380.78 per litre for another week. The government made adjustments in taxes and other levies to maintain the diesel price, which is otherwise considered on the higher side.
