The ruling Trinamool Congress on Sunday refused to attach much importance to BJP chief Amit Shah's rally in Kolkata and described it as a "grand flop show" with poor attendance.
"Such a meeting is organised by our block presidents," TMC secretary-general Partha Chatterjee said.
The TMC also claimed that despite BJP's attack on chief minister Mamata Banerjee, the country's ruling party would not be successful in tarnishing her image and honesty.
"The whole world knows about her honesty and there can't be any doubt," he said.
Chatterjee, who is also the state's higher education minister, alleged that the BJP was trying to disintegrate regional political parties by using power and police to maintain its political supremacy.
"BJP is now eyeing civic polls followed by the Assembly polls in 2016, but it will fail to achieve its target. BJP should now concentrate in Delhi before focussing on Kolkata (civic polls) and then West Bengal," Chatterjee said.
Another senior TMC leader and state panchayat minister Subrata Mukherjee said the rally was a "grand flop show" with poor attendance. "The BJP tried to bring many leaders from northern India, but failed to make it a success," he said.
Alleging that BJP was using CBI and NIA for political purposes, Mukherjee said, "Both the probe agencies have joined hands with the government in power at the Centre to help BJP maintain its supremacy.
"The BJP government should know that the Mamata Banerjee government initiated prompt action against the Saradha chit-fund scam and arrested Saradha Group chief Sudipto Sen, along with several others immediately.
"We have already returned money to over five lakh poor investors," he added.
