As India clocked 8.2% GDP growth rate in April-June quarter of the financial year 2018-19, former finance minister and senior Congress leader P Chidambaram said that he is happy that the rate of growth has quickened. He, however, pointed out that the GDP number reflects a higher growth than actual as the\u00a0growth rate is based on the lowest base (5.6%) in the last 8 quarters. "Going forward, the base effect will not be so favourable. And when we reach Q3 and Q4, the rate of growth may decline and the annual growth rate may be more or less like last year's," he tweeted.
