Jadhav, who appears to have sided with the rebel faction led by Ramesh Jarkiholi which threatened to topple the JD(S)-Congress coalition government in the state, is a two-time MLA from Chincholi in Kalbyrgi district, a bastion of senior Congress leader Mallikarjun Kharge.
Sources close to Jadhav told PTI he intends to join the BJP on Wednesday.
"He shouldn't forget that whatever he's today is because of Congress. Anyone can come and go but the party will remain forever," Rao told reporters.
He asserted that the other Congress MLAs will remain with the party.
The speaker is yet to take a call on that.
"Once disqualified, he cannot contest elections," Khandre said.
