Pakistan-born Canadian writer Tarek Fatah has given Delhi Chief Minister a tongue-lashing over the AAP convener’s protest against Prime Minister Narendra Modi’s much-debated move to demonetise Rs 500 and Rs 1000. A video shows Fatah berating CM Kejriwal, West Bengal Chief Minister Mamata Banerjee and former Jammu and Kashmir chief minister Omar Abdullah. “I can understand that Mamata Banerjee is opposing demonetisation move by PM Narendra Modi but how can Arvind Kejriwal oppose it,” Tarek Fatah opined. “Kejriwal comes from revenue services background, I don’t understand why he is opposing the demonetisation move,” Fatah said and dubbed Kejriwal as ‘idiot’. He also termed Omar Abdullah ‘pappu’ and mocked Banerjee.
