BIRATNAGAR: Federal Socialist Forum-Nepal (FSF-N) Chairperson Upendra Yadav said the unilateral amendment of the constitution was in no way acceptable to the agitating Madhesi parties. At a press conference in Biratnagar on Tuesday, Yadav asserted that the agitation would continue till the demands of United Democratic Madhesi Front were addressed. He further stated that the Madhesi parties would make a broader alliance in collaboration with pro-federal forces to enforce Madhes struggle. Saying the government was not serious to make dialogue a success, Yadav accused the government of supporting black-marketing.
