Karnataka deputy chief minister DK Shivakumar has criticized the Electronic Voting Machines (EVMs) controversy, arguing that they contributed to the BJP-JDS winning higher-than-expected seats in the state in recent Lok Sabha polls. Shivakumar called for an investigation into the use of EVMs and the return of ballot boxes. The controversy began with Tesla CEO Elon Musk urging the elimination of EVMs, while opposition leaders question their reliability.
