"People of Bengal will not forgive Mamata Banerjee if she obstructs entry of FDI in retail in the state. I hope she will not make such a mistake since FDI in retail is essential to boost our national economy," Bhattacharya told party rallyists who marched from Indira Gandhi's statue on the Maidan.
"It is a wrong notion, being deliberately touted to misdirect poor farmers, retailers and traders that FDI in retail would encroach on their livelihood," the PCC chief said.
Bhattacharya demanded that the the chief minister submit specific evidence about retail traders being affected by functioning of major domestic retailers.
"She has no authority to misguide the people and hurl abuses against the Congress-led UPA government," he said.
The WBPCC, he said, would call for a bigger rally shortly to project forcefully that FDI was required to boost the country's economy.
Bhattacharya and other PCC leaders, including Deepa Dasmunshi, also questioned the Trinamool Congress chief's 'closeness' with BJP and NDA leaders in opposing FDI.
