EC should address EVM concerns: Congress

The Congress on Tuesday rejected the BJP's charges of "sponsoring" Monday's controversial hackathon in London on EVMs and said that opposition parties for the last two-and-half years have persistently been raising the issue of tampering of the electronic voting machines but the EC has refused to resolve it.

Addressing the media here, Congress spokesperson Anand Sharma stood by the opposition's collective demand for returning to the ballot paper voting system and said the EC should address all EVM concerns.
