Congress leader P Chidambaram poked fun at the BJP Saturday over the GDP growth data, saying it did not warrant any jubilation by the ruling party. In a series of tweets, the former finance minister said that as expected, the GDP growth in the July-September quarter (Q2) of 2018-19 was a good one per cent lower than in the April-June quarter (Q1). "Q1 number was on a very low base in the previous year. It did not signify a bump in growth and did not warrant the jubilation of the BJP three months ago," he said. Chidambaram said going forward, it was likely that the October-December (Q3) and January-March (Q4) quarters would register similar growth rates unless there were unexpected shocks. "The new normal for the Indian economy is 7 per cent and 2018-19 will be a normal year," he said. India's economy grew at 7.1 per cent in the July-September quarter, lowest in three quarters, but still remained ahead of China to retain the tag of the world's fastest growing major economy. The Gross Domestic Product (GDP) at constant prices (2011-12) had grown at 6.3 per cent in the July-September quarter of the last fiscal, according to government data released Friday.
