"To allay apprehension of the people, PM should make his stand clear that the Naga peace accord does not affect the interest of Assam," he tweeted.
He said union minister Prakash Javadekar gave credit to Modi for Naga peace deal within 15 months of his assuming office.
"Will he also give credit to PM for depriving NE states of Special Category Status," he tweeted.
Gogoi yesterday welcomed the Naga peace agreement signed on August 3 and said, "We appreciate peace in Nagaland and welcome settlement of Naga issues, but we will oppose tooth and nail any move that affects the interests of Assam.
The Ministry of Home Affairs, he said, has even given the impression that it is in the dark about the details of the agreement.
"To keep such an important document under wraps raises doubt about its veracity. It also raises doubt that the peace deal might affect the interests of Assam, Manipur and Arunachal Pradesh," he added.
