Jaitley's comments come in the backdrop of an Indian cyber expert, who is seeking political asylum in the USA, claiming that the 2014 general election was "rigged" through EVMs, which are prone to hacking.

Meanwhile, the Electronic Corporation of India Ltd said on Tuesday that Shuja had not been an employee of the organisation, as claimed by him, PTI reported.
Whilst making several allegations, Shuja also alleged that BJP minister Gopinath Munde and veteran journalist Gauri Lankesh had threatened to expose the EVM hacking racket and were, as a effect, silenced.

He said the BJP would have won the recent Rajasthan, Chhattisgarh and Madhya Pradesh Assembly elections if his team hadn't intercepted the alleged attempts by the saffron party to hack the "transmissions" in these states.
Taking questions from journalists, however, Shuja reportedly failed to substantiate any of his claims.
