Mitra's self-defence came a day after Chief Minister Mamata Banerjee gave him a clean chit.
"I do not think that I have done anything wrong as some are trying to drag my name in the Saradha episode," Mitra told a private channel today.
Asked whether he was getting mental strength after Banerjee gave him a clean chit yesterday during a party meeting, Mitra said, "It seems that in the last 30 years, the Trinamool supremo had given him a "dark chit".
"I have always held my head high in front of the public and my chief minister considers that I am clean and clear as rays of the sun," he said.
Mitra's name was repeatedly linked with the Saradha Group which siphoned off crores of depositors' money -- a scam now being probed concurrently by the CBI and ED.
