The BJP today made big changes to its line-up of state in-charge, with what appeared to be focus on the states where elections are due in the next one year or less. BJP information technology cell chief Amit Malviya will now assist Kailash Vijayvargiya in handling West Bengal affairs. The BJP is looking to wrest the state from Mamata Banerjee's Trinamool Congress in the election due early next year.
