India's main opposition party, the Indian National Congress, has stepped up its attack on Prime Minister Narendra Modi in advance of general elections next year, alleging the government has failed to deliver on its promise of checking corruption and creating jobs. At the party's 84th plenary session that ended on Sunday, the Congress party leader Palaniappan Chidambaram said the country needed to be "rescued from the hands of incompetent economic managers". The Congress party has blamed Modi government for the mismanagement of the economy with polices such as demonetisation - that sucked out more than 80 percent of India's currency a year ago, stalling India's impressive economic growth. A Goods and Services Tax (GST) launched last year with much fanfare has drawn resentment from the business community – traditional supporters of Modi's Bharatiya Janata Party (BJP). Since Modi became prime minister in 2014, Congress party's influence has shrunk dramatically.
