An alliance of 29 Madhes and other small parties on Monday gave a 15-day deadline to Prime Minister Prachanda to table a proposal in Parliament to amend the new Constitution to address their grievences.
Sanghiya Gathabandhan of Janjati and Madhes parties have been protesting against the new Constitution, saying it marginalises them.
Sanghiya Samajwadi Forum Nepal Chairman Upendra Yadav submitted a reminder letter on the matter to Prachanda at his office in Singha Durbar on behalf of the alliance.
