The opposition Naga People's Front (NPF) on Wednesday said it cannot set an ultimatum on the negotiating parties of Naga political issue, though it desires an early settlement of the vexed problem.

The NPF statement came when peace talks are on to find a lasting solution to the seven-decade-old insurgency problem in Nagaland in New Delhi.

"We reiterate our stand that elected members as facilitators cannot put an ultimatum on the negotiating parties and comment on what to accept and what not in the final agreement. It is for the negotiating parties to sit together and hammer out differences and come out with a logical conclusion," NPF Legislature Party Spokesperson Imkong L Imchen in a statement here.

The Naga National Political Groups (NNPGs) — holding separate talks with the Centre since 2017 — had made an appeal on Monday not to maintain "neutral stand" and clear their position when the Government was keen to find a solution to the matter.

"There arises no question of the NPF, both from the organisational wing or the legislature wing, putting conditions for the final solution," Imchen said.

Earlier this month, Imchen said, during a meeting with Governor and the Centre's interlocutor RN Ravi, NPF Legislature Party TR Zeliang had urged him to work out a formula for the contentious issues of flag and constitution.

The on-going talks have been convened in Delhi in a bid to iron out differences, particularly on the NSCN-IM's demands for a separate flag and Constitution for the Nagas, which have already been rejected by the Centre.

"Unfortunately at this auspicious juncture, the NSCN-IM has adopted a procrastinating attitude to delay the settlement, raising the contentious symbolic issues of separate Naga national flag and Constitution on which they are fully aware of Government of India's position," Ravi had said in a statement last week.

Imcheng said, the NPF Party Central Executive Council had adopted a resolution in June on the Naga symbolic issues.
