New Delhi: A formal announcement about the proposed alliance between Aam Admi Party and Congress in Delhi may be made today. Congress president Rahul Gandhi who has returned to the national capital on Tuesday night may take the final call today on the alliance likelihood.

Earlier AICC in-charge of Delhi Congress and Delhi unit Chief Sheila Dixit held a meeting with Gandhi on Monday.

As per sources, the Congress is ready to give 4 seats to AAP in Delhi.

The AICC in-charge of Delhi Congress, PC Chacko on Tuesday said detailed discussions on the issue have taken place with the Congress president, who is currently in Rajasthan and his final word on the decision is awaited.

"He (Rahul) will return very late tonight. So, may be tomorrow he will tell us what to do. It (the decision on alliance) is likely tomorrow," Chacko said.

On Tuesday, Sheila Dikshit at a press conference, parried questions on alliance with the AAP.

"You will be informed when it happens," she said.

Dikshit who leads a section of her party leaders opposing alliance with AAP stopped short of voicing her stand.

As per sources, the leaders of Delhi Congress are divided over the issue with Dikshit, three working presidents Haroon Yusuf, Devender Yadav, and Rajesh Lilolthia and two former presidents of the unit Yoganand Shastri and JP Agarwal, opposing the alliance as it may hurt the party's interests in the long run.

However, the other side including Chacko, and former Delhi Congress presidents Ajay Maken, Tajdar Babar, Subhash Chopra, and Arvinder Singh Lovely favour a pre-poll tie-up with the AAP, citing the rationale to defeat the BJP in the Lok Sabha polls.
