The Trinamool Congress today demanded resignation of Chief Minister Buddhadeb Bhattacharjee and threatened to move a privilege motion against him after Bhattacharjee blamed the Trinamool for the killing of former CPM legislator Ananda Das in Nanoor on June 29.

Accusing the chief minister of “misleading the House”, Trinamool MLAs led by Leader of the Opposition Partho Chatterjee rushed to the well carrying placards written “Go away Buddha — leader of political clashes”, “Killer Buddha go away” and “Buddha resign”.

Slogan-shouting Trinamool members also encircled Speaker H A Halim’s table demanding they be allowed to speak.

Later, Chatterjee said the Nanoor incident was an “example of failure of police” and blamed the chief minister for it as Bhattacharjee holds the portfolio of Home department.

Chatterjee claimed that the killing of Das was a fallout of factional feud within the CPM and rivalry with the RSP, a major Left Front constituent.

On Thursday, senior RSP leaders had criticised the chief minister of handling the situation and pulled him up for “police non-performance”.

Meanwhile, state Congress chief Manas Bhuniya also accused the chief minister of

misleading the House and asked him to give up the Home department, “as he was overburdened”.

Bhuniya “ruled out” the hand of any Opposition party in the murder of Das, and demanded a CBI investigation into it. Bhuniya claimed the transfer of Birbhum SP Rabindranath Mukherjee, which the chief minister had announced in the House on Thursday, was in violation of a Supreme Court order and administrative procedures.
