Mumbai: India's former prime minister Manmohan Singh criticised his successor Narendra Modi's government in a rare interview, saying it has failed to capitalise on lower commodity prices to propel growth and is inconsistent in its policy towards neighbouring Pakistan.
Speaking to the India Today magazine, Singh said Modi's government should use improving fiscal balances to raise investment in the economy and increase the availability of credit to businesses.
"In the hands of a purposeful government, this could be an opportunity to step up investment in the economy in a big way," said Singh, who left office after a 2014 election loss.
Singh, regarded as the architect of economic reforms that led to years of rapid growth, said the government has not been able to take advantage of falling oil and commodity prices that have lowered India's import bill.
Sharp falls in import prices have reduced the trade deficit, raising hopes that it will boost economic activity. But turbo charged growth figures have been criticised by many analysts for giving too flattering a view.
The economy expanded 7.3 per cent in the quarter through December, but consumer inflation inched up unexpectedly last month and capital goods production, a proxy for investments, fell nearly 20 per cent in December.
Finance Minister Arun Jaitley wants to present a credible budget on February 29, people involved in the process say, but the government may end up breaking its budget deficit targets to stimulate demand.
In a rebuttal on his website and social media accounts, Jaitley blamed Singh's administration for mismanaging the economy, adding that the opposition Congress has been unwilling to support reforms in parliament.
"Both the Parliamentary Affairs Minister and myself have discussed the GST with every senior Congress leader in Parliament," he said, responding to Singh's criticism that the government has not consulted the opposition.
The proposed goods and services tax (GST), India's biggest revenue shake-up since independence in 1947, has been stuck in the upper house where it needs Congress' support to make it a law.
Singh also said Modi should focus on improving relations with neighbouring countries, adding that the government had not succeeded at making headway with Pakistan, which India accuses of supporting insurgents across their shared border.
"Certainly relations with major powers have improved... But I would say that the real test of foreign policy is in the handling of your neighbours. And here I would say that the Modi government's handling of Pakistan is inconsistent," 83-year old Singh told the magazine.
"It has been one step forward, two steps back."
Singh, an Oxbridge-educated economist, was credited as finance minister in 1991 for reforms that opened up the economy. But his legacy is marred by his final term marked by corruption scandals, ballooning inflation and slowing economic growth.
