The Congress has issued a three-line whip to its members in Lok Sabha asking them to be present during proceedings on December 7 and 8.

Parliament sources said this has been done not for any particular issue but keeping in view the possibility of some "important business".

The development has come at a time when Parliament has remained paralysed for the last nine days on several issues, including Foreign Direct Investment in retail.

The opposition has been demanding a rollback of the FDI decision and has been pressing for an adjournment motion on the issue so a censure the government.

Logjam has prevailed in Parliament despite government's efforts to placate its allies -- DMK and Trinamool Congress -- whose members vociferously protesting the FDI move.

The two Houses will now meet on Wednesday. The current session is slated to conclude on December 22.
