Party president M Karunanidhi wondered how the Centre would feel if it did not hike prices of petrol, diesel and LPG "once in two days".
"When will this stop? Should not the government work out a solution since this affects people. Is it the duty of a good government to show scant disregard to opposition criticism and keep on reivising prices endlessly," he said.
He said he felt "delicate" to even issue statements condemning the hike, "but those in the Centre are doing this price hike like (they are doing) a big achievement," he said, adding the Centre was "least bothered" about opposition criticism in this issue.
Oil Marketing Companies had revised the rate of non-subsidised LPG by Rs 220 per cylinder and that of petrol and diesl by 75 paisa and 50 paise, repsectively early this week.
