Accusing the Left of failing to protect investors in ponzi schemes during its prolonged rule in West Bengal, the Trinamool Congress today hit back after Left leaders met the Prime Minister and Finance minister seeking a CBI probe into the chit fund scam.

"Who are asking for a CBI probe today? It is those who were unable to pass an effective bill to rein in chitfund companies to protect the interests of small investors when they were in power from 1980 to mid 2011," Trinamool Congress Secretary-General Partha Chatterjee said.

Another TMC leader Derek O'Brien referred to the birth anniversary of Rabindranath Tagore that the state was celebrating. "On Rabindra Jayanti, a day Bengal celebrates Gurudeb Rabindranath and abjures politicking. True to form CPI(M) doesn't. It has resorted to dirty games," he said.

"Commies have complained to the President and demanded a CBI inquiry into the chit fund swindle they founded and promoted in then first place," he alleged. "Aside from the hypocrisy, couldn't CPI(M) have chosen another day? I suppose such cultural insensitivity comes easily to it," O'Brien said. "After all the CPI(M) is the party that threw out 'Sahaj Path' and lost Gurudeb's Nobel medal. His message is secondary to its politics," the MP said.
