"A grave conspiracy is on. US Secretary of State Hillary Clinton met Mamata Banerjee at Writers' Bulding on her way to New Delhi from Bangladesh," Bose said at a Left Front rally here.
"She also had a meeting with US Ambassador to India Nancy Powell recently," he said.
"No one knows what transpired at the meetings," Bose, a CPI(M) Politburo member, said.
"Mamata Banerjee is opposing FDI, but is not saying a word against America (USA)," he claimed.
"She is trying to show that she has hit the streets to protest FDI in multi-brand retail by holding the rally at Jantar Mantar today, but she had not opposed the move by the Centre earlier," Bose pointed out.
Bose claimed that Banerjee chose this day to hold her protest against FDI in multi-brand retail at Jantar Mantar in Delhi just because the Left Front had chosen to hold its protest against the Trinamool Congress government for alleged law and order breakdown in the state today.
"She (Mamata Banerjee) is trying to be more Left than the Leftists," he said.
"She chose the safer climes of Delhi instead of facing the rally and a delegation that had planned to meet the chief minister," he said.
