New Delhi, Jan 18 (IANS): BJP leader Arun Jaitley Saturday blamed the indecisiveness of Prime Minister Manmohan Singh for the poor economic situation in the country, and said it will be a "big challenge" for the BJP to manage the economy "when it comes in power".

"In this government, the real power was with someone, and the government was run by someone else. How can a weak prime minister make the economy strong," Jaitley said while presenting the economic resolution in the national council meet of the Bharatiya Janata Party (BJP) here.

"The economy has been ruined by the United Progressive Alliance and its corruption. It will be a big challenge for us and our allies to bring it back on track when we come in power," Jaitley, the leader of opposition in the Rajya Sabha, said.

Taking a jibe at Congress vice president Rahul Gandhi, without naming him, Jaitley said: "The Congress leader who was talking about the poor at Talkatora stadium, he should have known Congress's policies will never generate enough resources to help the poor."

The economic resolution, taken up by the council, blamed the UPA of wasting a decade that was crucial for the country.

"The country has witnessed a dark decade under the UPA regime," the resolution said.

It said the UPA inherited a "sound economy" from the BJP-led National Democratic Alliance government, and spoiled it.
