CPI(M) general secretary Sitaram Yechury made the remarks ahead of the Commission's EVM hacking challenge to be held on June 3 in Delhi to counter allegations of machine tampering during the recent polls.
Speaking to reporters in Delhi, Mr Yechury also reiterated that the Left party is for use of voter-verifiable paper audit trail (VVPAT) in EVMs in all the polls.
VVPAT is a machine which dispenses a slip with the symbol of the party for which a person has voted for. The slip drops in a box but the voter cannot take it home
The CPI(M) and NCP are the only two opposition parties which have agreed to participate in the Election Commission's challenge.
The Marxist leader also wondered why the challenge is being called "hackathon".
The challenge would take place on June 3 between 10 am and 2 pm at Nirvachan Sadan, the Election Commission headquarters.
The poll panel is set to hold the challenge after several opposition parties, including AAP and BSP, flagged concerns over the machines, particularly after Uttar Pradesh assembly elections and Delhi civic polls, contending the machines could be hacked.
