West Bengal chief minister Mamata Banerjee’s tussle with the Election Commission of India (ECI) and the central paramilitary forces, whom she has accused of working at the behest of the BJP, has entered a crucial phase. She stepped up her campaign after the death of four voters in Sitalkuchi, Cooch Behar, on April 10 and the ECI’s April 12 decision to ban her from campaigning for 24 hours for an earlier comment that the poll panel deemed was in violation of the model code of conduct.
