Thousands of Nepalese youths have launched a Facebook campaign to pressurise political parties to draft a new constitution by the May 28 deadline.

The campaign - We Nepalese united for change - called for stopping paying the politicians if they failed to draft the constitution by the deadline.

After the end of decade-long conflict between Maoist rebels and the state, Nepal elected a 601-member Constituent Assembly with a two-year mandate to draft a new constitution.

However, despite a 12-month extension agreed last year the lawmakers have failed to come out with the constitution.

Recently, youths, students, beauty queens and civil society members have gathered in numbers in front of the assembly building in Kathmandu to voice their concern.

"You have taken the wages and now its turn to give the constitution," reads one of the banners at the protest.

The youths have also asked the CA members either to ready the constitution by May 28 or to sacrifice their pays and perks and get only six months extension of the term for writing the constitution.

The coalition government has asked one more year of extension as it has admitted that constitution cannot be promulgated on May 28, the deadline set last year.
