The Communist Party of India-Marxist on Thursday said the Supreme Court order cancelling the 2G spectrum licences is a "strong indictment" of the government and asked Prime Minister Manmohan Singh to take a call on its fallout as it has exposed the "bluff" on the UPA-II's claims.

Demanding the resignation of Telecom Minister Kapil Sibal for claiming that there was no loss to the public exchequer, senior CPI-M leader Nilotpal Basu said, "The prime minister, who is known as a paragon of virtue, will have to take a call on the fallout of the judgement which has called the bluff on the government's claims on the 2G scam."

The verdict "absolutely puts the government under cloud.

The opposition and CPI-Ms charges have been upheld by the Supreme Court and earlier by the CAG, even though the prime minister's constant refrain has been that there has been absolute transparency. The court has totally rejected this, Basu added.
