The decision came Friday following a proposal by the Election Commission to raise expenditure limits for Lok Sabha elections to a maximum of Rs.70 lakh and a minimum of Rs.54 lakh, allowing candidates to spend more on their poll campaigns.
Observing that the decision will put "poor political parties" at a disadvantage, Banerjee said: "It will help the capitalist and large political parties who have enough money and can always spend crores for their election".
"The decision will clearly encourage more and more corruption and black-money," she added.
