Close on the heels of National Conference leader Omar Abdullah trashing the Congress-led charge against Electronic Voting Machines (EVM), another key Opposition party has dismissed the questions surrounding the machines. Trinamool Congress MP and general secretary Abhishek Banerjee has said those who doubt EVMs must demonstrate how they can be hacked. "The people who raise questions on EVM, if they have anything, they should go and show a demo to the Election Commission. If work is done properly at the time of EVM randomisation and people properly work at the booths during mock polls and counting, I don't think there is any substance in this allegation," he said.
