Prime Minister Manmohan Singh struck a downbeat note on the challenges facing the Indian economy on Thursday, dubbing a five-year plan for average growth of 8 percent "ambitious".
India's GDP growth has languished below 6 percent for three straight quarters, a far cry from the near-double-digit pace of expansion before the 2008 global financial downturn.
Economic growth for the fiscal year ending in March is expected to be 5.7-5.9 percent, India's slowest since 2002/03.

Analysts say the government must take more reform steps quickly, including speeding up the process for approval of investment projects, overhauling the tax system and reducing a swollen fiscal deficit by reining in its subsidy bill.
Singh said that subsidies on energy products should be limited, with a phased adjustment of prices.
"Unfortunately, energy is under-priced in our country. Our coal, petroleum products, and natural gas are priced well below international prices. This also means that electricity is effectively under-priced," he said.
"Immediate adjustment of prices to close the gap is not feasible, I realise this, but some phased price adjustment is necessary."
He added that early implementation of a Goods and Services Tax (GST), a long- delayed plan intended to replace myriad
