Kolkata, Feb 25 (IANS): Dismissing the newly-formed Third Front as a "daydream" of the communists, the Trinamool Congress Tuesday called it an attempt of these parties to exert their influence without responsibility.

"The Third Front is not just dead, it was never born," said Trinamool spokesperson Derek O'Brien said soon after 11 parties including four Left outfits came together to formally launch the grouping in Delhi.

"It is a hobby horse of the Communists, who want to use the power of regional parties to manipulate their way to influence without responsibility and to promote an obsolete agenda,' he said.

"The Third Front is a Communist day-dream," he added.

The Communist Party of India-Marxist, the Communist Party of India, and two other left parties - Revolutionary Socialist Party and All India Forward Bloc - are constituents of the Front which also includes the samajwadi party, trhe Janata Dal-United, AIADMK, and the Janata Dal-Secular.

CPI-M general secretary Prakash Karat said the Biju Janata Dal and the Asom Gana Parishad are also a part of the front.

Trinamool chief Mamata Banerjee has floated the idea of a Federal Front of regional parties, but it has not found many takers.
