The Indian economy likely expanded at its slowest pace in more than five years in the April-June quarter, driven by weak investment growth and sluggish demand, according to economists polled by Reuters.
That would reinforce concerns seen in the minutes from the central bank's August meeting, which showed policymakers were worried about weak growth and indicated further rate cuts in the next few months to boost the slowing economy.
The poll median showed the economy was expected to have grown at a year-on-year pace of 5.7% in the June quarter, a touch slower than 5.8% in the preceding three months. But a large minority - about 40% of nearly 65 economists - expect an expansion of 5.6% or lower.
The GDP data is due to be released at 1200 GMT on Friday.
If the forecast is realised, it would be the weakest start in the first three months of a fiscal year in seven years.
"The deceleration in growth that commenced in the second quarter of the fiscal year ending March 2019 is likely to have continued," said Rini Sen, India economist at ANZ.
"A host of high frequency indicators - consumption and investment - have continued to weaken. The most prominent ones include auto sales, output of consumer durables, cement and steel production."
