Kolkata, April 10 (IANS): West Bengal's ruling Trinamool Congress on Sunday approached the Election Commission for appropriate action over the alleged murder of one its workers, blaming vendetta politics of the combined opposition of the CPI-M and Congress.

"We have urged them to take appropriate action. Since the opposition knows they have no influence, they are resorting to vendetta politics," Trinamool Congress (TMC) general secretary Mukul Roy told the media here after meeting Chief Electoral Officer Sunil Gupta.

In addition, the party also urged the poll panel to ensure adequate security on the Jharkhand-Bengal and Odisha-Bengal borders during poll days, fearing presence of infiltrators.

On Saturday, the Trinamool demanded the immediate arrest of Congress candidate Manas Bhunia in the alleged murder of party worker Joydeb Jana in Sabang in West Midnapore.

"The Congress, CPI-M and the BJP know their campaign is having no impact on the ground. Hence they are resorting to bloody tactics of vendetta," the Trinamool said in a statement on Saturday.

"The local Congress candidate, Manas Bhuniya lodged a complaint against Joydeb Jana a few days ago. Even as late as yesterday (Friday) he was conducting enquiries, following up and plotting the murder. All evidence points to the fact. We demand he be booked as an accused in the case."
