DMK, a key ally of the UPA, Friday asked the Government to "roll back" the hike in petrol prices, saying the increase would have a "cascading effect".
"The hike in petrol prices will affect the lower and middle income groups and the poor. Government should not reduce the subsidy," DMK party spokesman TKS Elangovan said.
He said the increase should be rolled back as it would have "cascading effect" on the common man.
DMK is the second UPA ally after Mamta Banerjee led-Trinamul Congress to demand that the Government retrace its step.
