With reports of more Trinamool Congress MLAs preparing for a “right turn” in coming weeks, the Left and the Congress have demanded immediate summoning of the Bengal Assembly for the Mamata Banerjee Government to clear a trust motion.

Speaking to newsmen the Left and Congress leaders on Thursday said that it was the Government’s duty to seek a trust motion against the backdrop of wholesalemigration of TMC legislators to the BJP.

“Many TMC MLAs have crossed over to the BJP and there are reports of many more planning to go in the coming weeks. Against this backdrop there is a clear lack of clarity on who is on which side which is unprecedented in the history of State legislature…. It is being difficult to keep track on floor crossing. So we want the Government to summon the House immediately and prove its majority,” CPI(M) legislative party leader Sujan Chakrabarty said drawing severe criticism from both the ruling party and the BJP.

Congress and the State Leader of Opposition Abdul Mannan said there was the “Government is afraid to call a Session because it is suffering from trust deficit … it has no track of TMC MLAs as to which party they belong to now… Even the Speaker has no record regarding the MLAs’ political loyalty … this is the reason we are asking the Government to prove its majority on the floor of the House and clear the doubts from the mind of the people … it is only after the Trust Motion that the House and the entire people will be able to know the number of the MLAs supporting the Trinamool Congress today.”

The two parties have recently decided to fight the coming Lok Sabha elections together.

The TMC leadership however pooh-pooed the Left-Congress for “the ridiculous demand they are making to remain afloat in a thoroughly polarized atmosphere.”

Senior party leader and MLA Tapas Chatterjee said “the very demand only proves which part of the political spectrum two parties belong to these days and which kind of politics they are supporting today … The TMC’s secular credentials are tested and the people will clearly and read through their game plan. In public they talk of secular politics but their strategies prove something else. Their purpose will be defeated.”

Another senior leader and Minister Firhad Hakim said that the Left and the Congress were trying to play a “ridiculous game in order to bring back their relevance and stay afloat in Bengal. But the people of Bengal have rejected them. It is only Mamata Banerjee who is fighting for the cause of secularism in Bengal.”

BJP in its part tried to distance itself from the Left-Congress demand even as its leader Samik Bhattacharya said that his party would not come to power in the State from backdoor.

“We have nothing to do with such demands and we will like to come to power in the State through proper elections and popular mandate … This is a ploy of the Left and Congress which are nothing but signboards…

They want to win back relevance as a result of which they are making such demands. But the people know that the electoral atmosphere is currently divided between the BJP and the TMC … the fight is between the two parties in which the BJP will come to power with two hundred-plus seats.”

Meanwhile, in a related development the CBI officials probing cow smuggling and coal scam on Thursday raided houses of two Trinamool Congress youth wing leaders reportedly close to a top party functionary and an MP from South 24 Parganas.

The central agencies raided the Gariahat residence of businessman Vinay Mishra a TMC youth wing leader considered close to the stated MP who lives in South Kolkata, sources said even as the TMC leadership decried the CBI move as a ploy to malign party MP Abhishek Banerjee.

The Trinamool Congress businessmen-turned leaders have been asked to appear at the CBI office on January 4 sources said.
