Assam's beleaguered main opposition Asom Gana Parishad (AGP) Friday blamed "manipulation of electronic voting machines (EVM) by the ruling Congress party" for its rout in the assembly elections even as the Congress got a decisive mandate for a third successive term.

"We knew the Congress would do something and they did so by manipulating the EVMs. Otherwise such a result would not have come," former two-time chief minister and senior AGP leader Prafulla Kumar Mahanta told reporters.
