"The Chief Minister is openly threatening the opposition parties. We will be lodging a complaint today with the Election Commission. The Commission should take action against him," Mamata told media persons in Kolkata [ Images ].
"He is behaving like a dictator. He is vitiating the atmosphere. It is not desirable. EC should intervene," she said.
Asked if the Trinamool Congress has lodged complaint against any specific speech of Bhattacharjee, she replied, "We have recorded his utterances at different meetings and will lodge complaint on that basis."
On Saturday the chief minister had dared Trinamool to stop the Petroleum, Chemicals and Petrochemical Investment Region from coming up at Nayachar.
"I will see what strength they have. We have tolerated enough, we will not tolerate it any more," he vowed at an election meeting at Metiaburuz.
Mamata also suggested that the EC appoint a special observer to ensure a free and fair election in the state.
