The party also hit out at the Left for opposing the idea mooted by West Bengal Chief Minister Mamata Banerjee.
"The idea of a Federal Front is to provide an alternative to the people of the country after the 2014 parliamentary elections," senior Trinamool leader and party MP Sougata Roy told PTI.
Roy was reacting to CPI leader A B Bardhan's opposition to the Federal Front idea. The CPI veteran had said that such a platform would not neither be feasible nor would it would inspire people's confidence.
"Mr Bardhan is expressing the frustration of the Left as they are now irrelevant in national politics. At this moment, they are not in a dominant position anywhere or in any major state of the country," Roy, a former Union minister, said.
Asked if he thought Left leaders were trying to outdo Mamata by talking to SP chief Mulayam Singh Yadav and JD(U) president Sharad Yadav at a time when talks to form a non- Congress, non-BJP alternative were gaining ground, Roy said, "The Left is in no position to outdo Mamata at this stage."
