In a tweet in Kannada, Siddaramaiah wrote, “BJP was the first to raise doubts about the EVMs. The spokesperson of that party had even written a book. Supporting the doubt, LK Advani had written the preface of the book.

A poster Siddaramaiah tweeted says, “Concerns about EVMs are legitimate when raised by BJP!”

His tweet came in the backdrop of six posers by BJP national president Amit Shah to the opposition parties led by Andhra Pradesh Chief Minister N Chandrababu Naidu for raising doubts about the sanctity of EVMs.

In his tweets, Shah condemned those questioning the EVMs saying that opposing EVMs is an insult to the voters. By questioning the EVMs the 22 parties shaken with the possible loss were tarnishing the image of the country, he said.

Shah also questioned the political parties why did they assume power who were elected through EVMs and were now questioning its authenticity.

As many as 21 political parties Tuesday submitted a memorandum to the Election Commission asking it to first count the five VVPATs and tally with the EVMs before proceeding with the counting process for the Lok Sabha polls.

However, the EC turned down their plea.
