The no-holds barred attack against the BJP Prime Ministerial candidate came even as the ruling TMC demanded a public apology from him for doubting the integrity of Banerjee over the sale of her paintings and also complained to the Election Commission against him.
Rebutting the charge by her Gujarat counterpart that she had done more damage to West Bengal in 35 months of rule than the Left Front in 35 years, Banerjee also said that she did not need 'gyan' on development from the "architect of riots".
"The man who is being projected as PM candidate, if he comes to power, India will be ruined." she added.
On Modi's allegation that she was indulging in vote bank politics ignoring non-Bengalis and spreading the red carpet for Bangladeshis, Banerjee told reporters that he did not know history.
