T Muruganandham AIADMK general secretary J Jayalalithaa on Wednesday accused oil companies of imposing a bigger fuel price hike on consumers by compelling dealers to sell only premium variety of petrol and diesel. She said regular supply of ordinary petrol and diesel in all bunks was the need of the hour. She said that at a time when prices of essential commodities were going up following the re cent fuel price hike; oil companies had started imposing a further hike indirectly. Pointing out that the petroleum ministry did not fix prices of premium varieties of fuel and left it to the discretion of oil companies, Jayalalithaa said if the same situation continued, the prices of petrol and diesel would continue to go up without any formal announcement by the Centre. As a result, the prices of essential commodities would increase further, which in turn, would raise inflation, she said. Though the Centre hiked the price of petrol by Rs 5 and diesel by Rs 3, oil companies were selling premium fuel forcing people to pay Rs 9.70 for petrol and Rs 5.06 for diesel. She regretted that both the DMK government in the State and the UPA government at the Centre had remained mute spectators. Jayalalithaa demanded that the Centre take immediate steps to sell ordinary variety of petrol and diesel through all bunks.
