NEW DELHI: Congress president Sonia Gandhi on Thursday called Modi government 'arrogant' for ignoring Congress chief ministers before signing the Naga peace deal and accused the government of insulting the people of northeast.

"The accord may be historic, but the chief ministers of the state that would be directly affected were not consulted. Doesn't this show the arrogance of the government," Sonia told reporters.

"This government keeps on saying that it will take all the chief ministers together. But this step shows that the government is arrogant. It is an insult to the chief ministers and the people of the state," Sonia said.

"We're actually shocked,that PM didn't even think of taking into confidence our CMs. He did not even think of taking into confidence our Manipur CM, Assam CM, Arunachal Pradesh CM who are directly affected," Sonia Gandhi said hitting out at PM Narendra Modi.
