"It seems that the Left supporters who had voted for our candidates earlier have not voted for us this time. They are so desperate in removing Trinamool Congress that they opted to vote for BJP," Mishra told reporters here.
"Not only the Left Front supporters but voters of other parties, including those from the ruling party where there is internal feud have voted for BJP," he said.
Describing the rise of BJP in Bengal in the last couple of years as "dangerous", Mishra held the ruling TMC responsible for it.
"The rise of BJP is nation-wide and it is also happening in the state, which is quite dangerous. Their (BJP) rise is dangerous for the country as well as for the state. In West Bengal BJP has grown under the tutelage of TMC owing to their mutual understanding," the CPI(M) leader said.
