WB CM Mamata asks booth agents to guard EVMs round-the-clock

West Bengal CM Mamata Banerjee appealed to voters and booth agents to thoroughly check EVMs as state elections approach, alleging that BJP will hack votes. "I know [the BJP's] plan...after voting, under the watch of CRPF and central forces, they might go inside and change the machines," she said. She further said surveillance needs to be kept for 24 hours.
