Speaking to reporters, Karunanidhi said, "We will debate the issue with the government and persuade them to reduce the price. We hope that at least the price of diesel, used by farmers will be reduced."
When asked if his party would 'fight' against fuel price hike as other Opposition parties were doing, he said the government had its own pressures when it decided to raise the prices.
Last week, Karunanidhi had written to UPA Chairperson Sonia Gandhi, Prime Minister Manmohan Singh and Finance Minister Pranab Mukherjee.
In his letter, Karunanidhi had said that the hike would have a cascading effect, further pushing up prices of essential commodities.
Apart from DMK, another UPA constituent Trinamool Congress, has also come out strongly against the hike and demanded that it be rolled back.
