Senior Congress leader P. Chidambaram on Sunday attacked Prime Minister Narendra Modi on lack of job creation and said jobs would be a critical factor in polls over the next 16 months, including the Lok Sabha election. In a series of tweets, the former Finance Minister said the Bharatiya Janata Party (BJP) under Modi's leadership was not unbeatable as was proved in Delhi and Bihar and that "a strong narrative and a carefully-crafted strategy" can defeat the BJP again.
