Party sources said the whip has been issued in connection with the key reform bill, which has been high on the government's agenda but stalled by Congress over some provisions.
To bring Congress on board, the government last week cleared changes in the constitutional amendment bill, including doing away with the additional 1 per cent tax by producing states and compensating all states for any revenue loss in the first five years post the GST roll out.
BJP parliamentary party is also meeting tomorrow and senior ministers may brief the members about the bill and other important issues on the agenda in the coming days.
