RAJBIRAJ: Nepali Congress Treasurer Sita Devi Yadav has warned that the party's political journey in Tarai would end if the demands of the Madhes-based parties were not addressed. Speaking at a greetings exchange programme in Rajbiraj, Yadav claimed that any more delay in addressing the demands would result into a chaos. 'Enough blood has been spilt in the name of rights,' she added, 'There should not be any delay in the Constitution amendment.' She stressed that issues of citizenship, proportional representation, inclusion and provincial demarcation among others raised during the then party President Sushil Koirala's government must be addressed at the earliest. Making her stand clear on the matter, Yadav said that the NC needed to take an initiative to retain its position.
