"We have issued a whip and asked all the members to be present tomorrow. There is already a clash between the government and the opposition; we want to be in our full strength even on Friday, which is normally a day for Private Member Bills," said Satyabrat Chaturvedi, Congress's chief whip in Rajya Sabha.
Asked about the development, the deputy leader of Congress in the House, Anand Sharma, said the party had acted thus as a matter of precaution since BJP has in the past slipped through certain legislative business in the other House, bypassing the Business Advisory Committee.
The whip is to ensure that the government does not succeed in getting measures passed taking advantage of the absence of opposition members, they said.
Several key legislations, including the one on GST, which is a Constitution-amendment Bill, are held up due to the current impasse in Parliament.
