For the first time in almost two years, the government on Friday slashed petrol price by Rs 5 a litre and diesel by Rs 2 and dropped broad hints of more cuts before the general elections are announced early next year. Petrol in Delhi will cost Rs 45.62 a litre from Friday midnight as against Rs 50.62 currently, while diesel will be cheaper by Rs 2 per litre at Rs 32.86. There will be no change in the prices of LPG (cooking gas) and kerosene.
