"Both the decisions of hiking the diesel price and restricting the supply of subsidised cooking to six cylinders per household in a year are going to hit the common people badly," he told reporters at the airport here.
"CPI-M has already strongly criticised the decision of the Centre. We are going to discuss with other parties as to how to organise a common movement to demand the rollback of the decision," he said.
Karat was here in connection with a CPI-M state committee meeting.
The government yesterday hiked diesel prices by a steep Rs 5.62 per litre and restricted the supply of subsidised cooking gas to 6 cylinders per household in a year to fetch an additional Rs 20,300 crore.
