The six-member delegation of the Trinamool Congress (TMC) met the full EC team, including Chief Election Commissioner (CEC) Sunil Arora, for over an hour and submitted a memorandum to it, highlighting how BJP leaders in West Bengal had threatened the chief minister through tweets and other remarks.
