"Mamata knows very well that she can't move the motion alone. Therefore she is banking on support of communal forces like BJP and arch-rival Marxists. This is nothing but lack of sense and principle in politics," WBPCC president Pradip Bhattacharya told reporters in Kolkata.
He alleged that this "friendship between unequals" was only for 'convenience' at the cost of political ideology and principle just to "wipe out" Congress.
"With this attitude, Banerjee will have no credibility left to fight against either the BJP or the Marxists," he pointed out.
The state congress would observe a "Dhikkar Divas" (Condemnation Day)" on November 22, the day Parliament reconvenes and when the TMC planes to move the no-confidence motion, he said.
Announcing on Saturday her party's decision to move a no-confidence motion, Mamata said she was ready to talk to the BJP, the CPI(M) and other Left parties, if they want.
