BJP chief Amit Shah triggered a political storm in Bengal today, claiming at a rally that the Mamata Banerjee's government has reduced "Sonar Bangla (Golden Bengal)" to "Kangal Bangla (Beggar Bengal)". It infuriated the state's ruling Trinamool Congress, whose chief lashed out at Mr Shah, calling him a "fathead" and citing the Gujarat riots. Tweeting under the hashtag "#LowLife", senior party leader Derek O'Brien called him "puke-worthy". "He (Amit Shah) is a fat-head. Half-literate. All they know is how to start a riot... I'm willing to lay down my life, but there will no riot under my watch," said Mamata Banerjee, who had earlier accused Prime Minister and his party of using unparliamentary language and lowering the political discourse.
