"The justification of our call for a statewide bandh on September 20 demanding withdrawal of hike in diesel price, LPG cap and FDI entry in retail, is quite clear from Mamata Banerjee's decision (to pull out of UPA)," CPI(M) state secretary Biman Bose said.
"The chief minister should try to understand that we have been constrained to call the bandh on anti-people issues," he said.
Bose, who is also the Left Front chairman, said that he expected the state government would not oppose the September 20 shutdown.
