New Delhi (PTI): The BJP on Friday took a swipe at the Congress over its leader P Chidambaram's remark on the opposition INDIA alliance, saying even Rahul Gandhi's "close aide" know that the party has no future.

Chidambaram had on Thursday voiced concerns over the INDIA bloc, saying he was not sure if the opposition alliance was still intact.

Latching on to Chidambaram's remarks, BJP national spokesperson Pradeep Bhandari said in a post on X, "Congress Leader P Chidambaram predicts: 'Opposition will not be intact in future, BJP is a formidable organisation'."

"Even Rahul Gandhi's close aides know Congress has no future," he added.

Speaking at the launch of Salman Khurshid and Mritunjay Singh Yadav's book "Contesting Democratic Deficit", Chidambaram said, "The future (of INDIA bloc) is not so bright, as Mritunjay Singh Yadav said. He seems to feel that the alliance is still intact, but I am not sure".

"It is only Salman (Khurshid) who can answer because he was part of the negotiating team for the INDIA bloc. If the alliance is totally intact, I will be very happy. But it shows at the seams that it is frayed," the Rajya Sabha MP said.

He also hoped that the alliance can "still be put together, there's still time".

The former Union finance minister warned that the INDIA bloc was fighting against a "formidable machinery", which must be fought on all fronts.

The Indian National Developmental Inclusive Alliance (INDIA) of opposition parties came together ahead of the last Lok Sabha elections to counter the BJP-led National Democratic Alliance at the Centre.
