Karat said, "we do not want to stall parliamentary proceedings but there can be no compromise on the demand for the JPC probe. If the UPA government does not allow a probe, people's suspicion on the government's involvement in the scam will go up."
"Since Independence this (2G spectrum allocation) is the biggest scam in the country and the Parliament has every right to inquire into it," he added.
Karat also blamed the government for the skyrocketing prices and slammed its inaction to curb the increase in prices of food and other essentials.
He said, "the United Progressive Alliance government's wrong policies were responsible for the skyrocketing prices, which was the biggest attack on the citizens."
Karat even lambasted BJP leaders for failing to fulfil its role as the main Opposition party of the country. He said, “it is highlighting the corruption of Congress but when it comes to corruption in its own states, the party is silent."
"Both the Congress and the BJP are working for the benefit of the capitalists, while CPI-M and the other Left parties are working for the benefit of the common people," Karat said.
Karat alleged that probes into the Malegaon, Mecca Masjidand Ajmer Sharif blasts as well as Swami Aseemanand's depositions in the court clearly proved that BJP and RSS had links with those involved in ''Hindu terrorism''.
"Our fight against both Hindu terror and Islamic fundamentalism will continue," he added.
