Finance minister Nirmala Sitharaman on Friday asserted that the measures taken by the government to reverse the economic slowdown have begun to bear fruit and pledged to respond with more steps, if required. The GDP growth crashed to an over six-year low of 4.5% in the September quarter. The minister also countered speculations about a restructuring of the GST slabs of 5%, 12%, 18% and 28% to address a big shortfall in collections, saying the finance ministry hasn’t yet discussed any such issue. “Buzz is everywhere other than my office,” she remarked, but did not rule out a hike in GST rates of some items.
