The Centre should stick to the fiscal deficit target for 2018-19 and continue with the reforms undertaken during the over four years of the Narendra Modi-led government, former Niti Aayog Vice Chairman Arvind Panagariya said Sunday. The present government, Panagariya said, has made a huge progress in implementing reforms including some difficult structural ones such as the Goods and Services Tax (GST) and Insolvency and Bankruptcy Code (IBC) that previous governments had difficulty in introducing.
