"Today there is a talk of an understanding with them in view of elections. You can sup with devil for elections... This is a betrayal of the nation," party spokesman Salman Khurshid told reporters referring to reported statements made by Union minister and BJP leader Kiren Rijiju.
Khurshid said that the Congress has made great sacrifices for the cause of Kashmir. "These are not only political sacrifices, but greater sacrifices".
Rijiju denied having said anything on Kashmir separatists or polls.
BJP has also denied having met separatists in Jammu and Kashmir in the run-up to assembly elections.
