"We have informed AICC about the turn of events and the kind of anti-party activity that Manas Bhunia has indulged in. We have urged Bhunia to immediately tender his resignation from the post of PAC chairman," a senior Congress leader said on condition of anonymity.
Bhunia was yesterday appointed chairman of PAC in West Bengal Assembly amid opposition by his own party which wanted to offer the post to CPI-M leader Sujan Chakrabarty.
State Congress President Adhir Chowdhury asked Bhunia to tender his resignation.
When contacted Bhunia refused to comment.
Bhunia's name was announced as the chairman of the PAC by Speaker Biman Banerjee following which Congress and the Left Front walked out of the House in protest.
The Speaker later told reporters he had followed the convention by offering the post to the main opposition and followed the rule 255 A.
