NEW DELHI: Former PM Manmohan Singh on Friday said the Modi government had failed on all fronts - economic, agrarian and relations with neighbours - and people were not impressed by the official claims of development.Speaking at the launch of Congress leader Kapil Sibal 's book "Shades of truth - a journey derailed", Singh said, "The government has not constructively dealt with the agrarian crisis facing the nation. Farmers are still not assured of receiving the remunerative prices of their produce".Singh said Sibal's book was a comprehensive analysis of the functioning of the Modi government in the last four years. "It highlights the failure of this government to fulfil promises made to the people on the eve of 2014 Lok Sabha elections ," he said.Referring to the PM's 2014 promise of providing two crore jobs per year, Singh said the employment growth rate has been declining in the last four years.
