Election Commission will organize EVM challenge in New Delhi tomorrow where political parties will try to prove that the machines can be rigged. Only the Nationalist Congress Party and the CPI(M) have shown willingness to participate in the challenge.<br/><br/>The Commission has pulled out 14 Electronic Voting Machines for the challenge from its strong rooms in Uttar Pradesh, Punjab and Uttarakhand where assembly polls held recently.<br/><br/>The challengers will get four hours each to tamper with the machines. The challenge will begin at 10 AM and end at 2 PM. The members of a technical committee which helps the EC evaluate the EVMs would judge the proceedings. Each participating party can use a maximum of four EVMs for the challenge.<br/><br/>Meanwhile, CPI(M) said, it will not try to hack EVM during the challenge, but will suggest precautionary measures to ensure transparent polls.<br/><br/>After the UP assembly polls, BSP, Aam Aadmi Party, Congress and others had questioned the EVMs alleging that they were tampered with. However, when the poll body invited all parties to participate in the challenge the AAP and Congress raising some issue with the existing framework of challenge decided not to take part.<br/><br/>But, the Aam Admi Party has planned to organize its own EVM challenge on the same day to show that EVMs can be tampered with.
