Although fourth in vote count, the Congress is looking at Sena to take a call, even as its longtime former ally NCP has completely ruled out joining the combine if Shiv Sena is ushered in.
General Secretary in-charge of the state Mallikarjun Kharge will chair the meeting scheduled at 5 p.m. Former Chief Ministers Ashok Chavan and Prithviraj Chavan will also be present.
Congress on Tuesday maintained that the party could think of stitching up an alliance with the Shiv Sena, even.
"We can think of supporting the Shiv Sena but Uddhav Thackeray has to decide first on the issue... whether he wants to break away from the BJP or not," party leader Hussain Dalwai told .
Having come fourth with 44 seats in the recently-concluded Assembly elections on October 21, the party is not in a position to move forward but waiting for the right signals from the Sena.
In the latest developments, the Sena cancelled the meet with the BJP on government formation. It has maintained that it wants a written assurance from the BJP on a rotational Chief Minister.
The Congress is questioning differences between friends who are now targeting each other.
Former Chief Minister Prithviraj Chavan also reiterated that there is no proposal from the Sena yet, and asked the BJP and the Sena to make the deal between them public.
Maharashtra Congress spokesperson Sachin Sawant told that "there is no proposal from the Shiv Sena yet". "If they approach us, we will talk to our high command in Delhi before taking any decision".
The Congress high command is, however, cautious on the ongoing battle between the two parties, with leaders in Delhi saying that the Sena may not take the extreme step of dumping the BJP.
A senior leader, speaking on the condition of anonymity, revealed that there was "a back-channel deliberation" with the Shiv Sena, but it has not "kicked off" as yet.
A Shiv Sena-Nationalist Congress Party-Congress combine is a scenario being floated by some Congress leaders in Mumbai, but the party is wary about any such combinations.
The Congress will only move ahead when Uddhav Thackeray leaves the BJP officially, a leader said.
With the Congress-NCP combine ruling the state for 15 years before being swept out of power in 2014, the Congress' strategy will also depend on the moves of NCP supremo Sharad Pawar, whose party is the senior partner in the state in terms of seats.
However, Pawar has maintained that there is no chance of the NCP supporting the Shiv Sena's bid to form a government. "This is not an option before us. People have asked us to sit in opposition. We have accepted the mandate," he had said.
Pawar's statement has given some relief to the BJP, which is at loggerheads with its partner on the issue of Chief Minister's post.
Dalwai, however, said that "politics is game of possibilities".
