Trinamool Congress chief Mamata Banerjee showed "political immaturity" in moving a no-trust motion against the UPA-II government with just 19 MPs in her fold, Left Front chairman Biman Bose said on Friday.
"Though she was aware that her no-trust motion will find no taker among other political parties, she went ahead in moving the motion in the Lok Sabha yesterday, which fell through for want of the required numbers," Bose said at a news conference in Kolkata.
He said since Banerjee had already made public her party's intention to move the no-confidence motion, she had to maintain that stance knowing fully well that it would not get admitted.
"This shows her lack of political maturity. Our party does not function in that manner. We test the waters before hand," he said.
Bose said Banerjee had sought Communist Party of India-Marxist support for the motion, but the party did not agree because together with the Trinamool, the requisite number would have still been elusive.
"That is why we decided not to support the motion and instead sought a discussion on FDI under Rule 184. Other parties were also thinking on the same lines," he said.
Bose said such a move would have been more feasible in cornering the government as many parties would have supported the move because they were opposed to FDI in retail and at the same time not keen in pulling it down.
To a query, he said during the UPA-I regime, the CPI-M had moved a no-confidence motion since it had the requisite strength with 61 MPs. "But the case this time is not the same," he said.
"However, we will continue our campaign against FDI in retail," he said.
At a meeting of the Left Front on Friday, it was decided to start a 50-day signature campaign on food security across the state from December 3 till January 25.
