Noting that Parliament had a very heavy legislative agenda during the Winter Session, Singh said, "I seek cooperation from my collegaues in the House to come together and address the issues and challenges that we face as a nation".
The Prime Minister said the government was ready to discuss all the issues on the floor of both the Houses.
"We all have an obligation, in Opposition as well as in government, to work together to enable our parliamentary democracy, of which we are genuinely proud of, to grapple with the formidable challenges facing our country," Singh told reporters outside Parliament House.
He said the country was faced with many problems on the economic front arising out of the consequences of global economic slowdown.
"We need to create new jobs on a large-enough scale to provide gainful employment to our youth. We need to increase investments in infrastructure sectors and social services like health and education to accelerate the tempo of economic growth," he said.
The Prime Minister said the government was committed to these tasks but its success required cohesive collective action on the part of all segments of polity.
"I invite all political parties to join hands in this vital national endeavour," Singh said.
