Speaking at the All India Congress Committee meeting here, he said gross domestic product and agricultural growth rate were faster during the eight-year United Progressive Alliance government (UPA) compared to the six years of National Democratic Alliance (NDA) government.
He said the government had not received all the credit for its work due to shortcomings in its communication strategy.
"Probably, our communication strategy is not very effective," Manmohan Singh said, adding that there was a need to communicate the success of the government effectively.
He said some opposition-ruled states had claimed credit for central schemes and Congress workers needed to explain the correct picture to the people.
