The Trinamul-led state and BJP-led central governments are lining up their own events to observe Netaji Subhas Chandra Bose’s birth anniversary on January 23, intensifying the tug of war over one of Bengal’s foremost icons. Sources close to Mamata Banerjee said she would try and steal a march over the Prime Minister by hosting the state’s events before those of the Centre begin, on Saturday in Calcutta. On Tuesday, the Centre declared January 23 as Parakram Diwas (Valour Day). The railway ministry also decided to rename the Howrah-Kalka Mail as Netaji Express. Mamata professed displeasure over the word parakram, asserting deshprem (patriotism) or deshnayak (national hero) would have been better.
