KATHMANDU: Former Prime Minister and president of the Rastriya Janashakti Party (RJP) Surya Bahadur Thapa today urged the major political parties to reach consensus on constitution-making process. Celebrating his 83rd birthday at his Maligaon residence with close relatives and friends, Thapa told the media persons that the time for writing the new constitution was fast approaching and the major parties had not been able to assure the people and international community that they will succeed in adopting it on time. If the Constituent Assembly failed to adopt the constitution on time, people’s morale will go down and the nation will face unprecedented political crisis. “Instead of fighting for power, the parties need to utilise the limited time that they have on constitution-drafting process,” Thapa said. When asked to elaborate on the post-May 28 scenario, the former PM said the major parties might either agree on extending the tenure of the Constituent Assembly or adopt a “brief constitution”.
