Probably Prime Minister Narendra Modi never expected such a strong opposition to demonetization from Trinamool Congress supremo Mamata Banerjee. The Prime Minister had expected that most of the opposition leaders would never oppose any strong action against black money hoarders, but on Tuesday, when Congress vice-president Rahul Gandhi and Mamata Banerjee came on a single platform to oppose demonetization, it surprised even a seasoned politician like Modi. It is, however, coincidence that the CBI on Tuesday sent notices to two Trinamool Congress leaders, Sudip Bandopadhyay and Tapas Pal, summoning them for questioning related to chit fund scam. Among the public, Mamata has carefully cultivated her image of an honest leader, a fighter and aggressive leader. But in the last few years, several of her party leaders including MLAs and MPs have gone to jail on charges of being involved in chit fund scams. Mamata Banerjee has to openly defend her leaders, and there lies her dilemma.
