"We cannot say tampering (with EVMs) has taken place in these elections," he said, buouyed by the victory of the Congress candidates in the Nanjangud and Gundlupet Assembly by-polls, in which the party retained both the seats in spite of a tough fight by the BJP.
His party had only spoken about the "scope" for tampering, Siddaramaiah told reporters when asked about his stand on EVMs in the light of the outcome of the by-polls.
Siddaramaiah said he was told that the EVMs used in the two by-polls had Voter Verifiable Paper Audit Trail (VVPAT).
His remarks come against the backdrop of a campaign launched by the Congress-led opposition on alleged EVM tampering after a string of defeats in the Assembly polls, including in Uttar Pradesh where the party was decimated.

Punjab Chief Minister Amarinder Singh too has toed a different line from that of his party and is quoted to have said, "If the EVMs were fixed, I wouldn't be sitting here. The Akalis would be."
The EC has thrown a gauntlet at the political parties challenging the EVMs, daring them to try to hack the machines and show that they can be tampered with.
The challenge will be open for a week or 10 days.
