The Congress on Wednesday took a swipe at the Centre over Home Minister Amit Shah's remarks hailing the Narendra Modi government's "relentless efforts to establish permanent peace in the Northeast", saying a visit by the prime minister to Manipur which has seen so much turmoil is called for as part of these "so-called efforts".

Congress general secretary Jairam Ramesh's attack on the government came after Home Minister Shah announced that the United National Liberation Front (UNLF), an extremist group operating in Manipur, signed a peace agreement with the government and agreed to renounce violence.
