Bengal Chief Minister Mamata Banerjee will "protest the undemocratic and unconstitutional decision of the Election Commission" - to hand her a 24-hour ban - at noon today. The Chief Minister's sharp tweet came less than an hour after the poll body suspended her from campaigning - as she seeks to defeat the BJP in an election that is balanced on a knife's edge - over comments on Muslim votes and those allegedly urging a revolt against central security forces.
