Rashtriya Janata Dal (RJD) leader Tejashwi Yadav on Monday released his party's manifesto 'Pratibadhta Patra' for the upcoming Lok Sabha elections. "RJD has always favoured reservation in private sector. We will ensure it becomes a reality," Tejashwi said. The manifesto promises to fill vacant government posts, take steps to stop migration and implement the Mandal Commission, among others.
