Twenty-one years after officially separating from the Congress, Mamata Banerjee-led TMC has removed the grand old party's name from its logo. The new logo has Trinamool written in green with twin flowers and blue background. It has been in use for a week now, party sources said. It was way back in 1998 that Mamata broke away from the Congress and formed the TMC over differences of opinion on dealing with the then ruling CPI(M). A party leader said that the Congress name has been dropped from party banners, posters and all communication material. However, it will remain registered with the Election Commission as Trinamool Congress, party sources said. The official Facebook and Twitter pages of the party, the CM, her nephew Abhishek Banerjee, and Trinamool's leader in the Rajya Sabha Derek O Brien already have the new logo.
