"If any functionary of our party (CPI-M) is proved guilty of involvement in the chit fund scam he or she will not be spared, action will be taken against him," he said.
Bose, who was reacting to media reports that he had attended the wedding of the daughter of MPS group chairman Pramath Nath Manna, said from now onwards he would not attend such ceremonies or functions hosted by persons about whom he was not well aware of.
"I knew Mr Manna as a person who used to run food processing units. So when he invited me for his daughter's marriage ceremony I attended the function. I was not aware of his chit fund business. From now onwards I won't be attending a marriage invitation of any such person whom I don't know properly, except my party workers with whom I work. If someone invites me for a wedding I generally attend it. I just have a cup of coffee or tea there," said Bose.
Bose also said that those who are 'trying' to put in the same bracket his attending the wedding with those reported incidents of politicians taking money from ponzi scheme companies are playing 'dirty politics'.
"My attending a wedding and a section of politicians taking money from chit fund companies or having special meetings with owners of such companies should not be equated," he added.
