Senior Congress leader Digvijaya Singh on Sunday alleged that Electronic Voting Machines (EVMs) can be tampered with prior to being deployed. Singh in a tweet said that there was a strong possibility of tampering with coding at the time of writing the software for the EVMs. "EC limiting objections to EVM to
hacking. It must allow examination of possibility of software tampering at stage of writing it from server," he said on Twitter. "EC must devise a way of supervision by Political Parties at the (stage) of coding software to EVM. Like it does at subsequent stages. Would they?" Singh said in another tweet.
