NEW DELHI: Even before the announcement of polls on February 26, the Election Commission had started receiving letters from West Bengal chief minister Mamata Banerjee expressing misgivings about electronic voting machines (EVMs) and voter verifiable paper audit trail (VVPAT) and even demanding a third-party audit of the results. Three separate letters were written by Banerjee on February 6, February 24 and March 2, demanding, among other things, independent third-party audit of results with findings to be made public, 100% tallying of EVM count with VVPAT slips and ordering repoll in the event of a mismatch; and increasing display time of VVPAT slips from the current 7 seconds to 15 seconds and also allowing the voter to cancel his/her vote in case of any discrepancy. “With the fierce rivalry of opposition political parties looking to win by hook or crook...tampering of EVMs and VVPATs is not unlikely in West Bengal assembly,” she had noted while suggesting these “solutions”.
