"I am confident that the deadlock will be resolved within two-three days. The result of our efforts will come out soon and the constitution drafting project will be a success.
"All political parties have realised that they should take initiatives to resolve the deadlock after Constitution Assembly Chairman Subas Nembang began his active engagements in the constitution drafting," Koirala said.
The constitution drafting is the priority of all political parties at present, he said and pointed out the need to lead the country towards the path of overall development by first drafting the constitution.
"What happens if we fail now? It will lead to some bad consequences," he said while addressing a function organised to honour Chief Justice Ram Kumar Shah here.
"Vandalism, protests or destructions are not desirable. The rights of all the Adivasis or Janajatis, women, Muslims, minorities and different religious and lingual groups will be ensured in this constitution," Koirala said.
Political parties in Nepal have set a January 22 deadline to draft a constitution so as to institutionalise the achievements of the Peoples Movement of 2006.
