Sources said, in a telephonic conversation with Azad, the Information and Broadcasting Minister, who earlier held the charge of Parliamentary Affairs, sought Congress' support for the passage of the GST bill.
The government has also proposed holding talks with opposition Congress to iron out differences on the issue. A meeting of top Congress leaders like Azad and Anand Sharma with Finance Minister Arun Jaitley on the issue is likely to be held in a day or two.
Top Congress leaders had yesterday deliberted on the strategy for the session with party president Sonia Gandhi at her residence where GST was also discussed.
Congress has been pressing for a GST cap of 18 per cent as part of the Constitutional Amendment bill with which the government is not in agreement.
