Away from public events and high-voltage election rallies, the battle for Bengal now includes the legacy of iconic freedom fighter Netaji Subhash Chandra Bose, with the ruling Trinamool and the opposition BJP squabbling over what to call and how to celebrate his 125th birth anniversary. On Saturday morning, hours before Prime Minister Narendra Modi is due in Kolkata to take part in a series of cultural events to honour Netaji's memory, Bengal Chief Minister Mamata Banerjee took a swipe at the centre over its decision to call the day 'Parakram Diwas'; the Bengal government wanted the label 'DeshnayakDiwas' - a nod to the Rabindranath Tagore connection.
