Yechury also dismissed Singh's assertion that action will be taken within 90 days against people involved in Commonwealth Games scam, saying "we have heard these things many times before."
The CPI(M) Politburo member said the Prime Minister did know about the irregularities in the spectrum allocation as early as in 2007 when the Left parties, which were outside supporters of the UPA-I government, had written to him pointing this out.
His party colleague Brinda Karat said, "It is absolutely shocking that the Prime Minister holds a press conference. The country expect him to come out absolutely clearly and strongly that what happened with 2G scam was wrong and that he regrets the wrong-doing."
"But what did he say? On one hand, he actually defended both the policies and the procedures (of 2G spectrum allocation) and even the immediate sale of equity of two companies through huge amounts. He actually defended it saying this was just a way of raising funds from the market."
She said when the Supreme Court and the CBI were waiting for the government to take action against the companies which got the licences illegally, "the Prime Minister, in fact, almost put out a defence for them."
Singh also said there were coalition compulsions, Karat added.
