JHAPA: Nepali Congress leader Krishna Prasad Sitaula on Friday said the country’s development was possible only if all major parties worked in unison. Inaugurating the Mechi-Mahakali Mountain, Hill and Tarai National Campaign at Jhapa’s Kechana, Sitaula stressed on the need for unity among the major political parties. “How can the statute be implemented if the leaders who promulgated it stand poles apart?” Sitaula asked. He said political instability was delaying the country’s development. He said polls of provinces and local bodies were not possible without formation of a national government.
