Congress on Wednesday appointed former IPS officer Ajoy Kumar in-charge of Nagaland, Sikkim and Tripura, with immediate effect. Kumar was an MP from Jamshedpur in the 15th Lok Sabha. He had quit the party to join the AAP ahead of the Jharkhand assembly polls in 2019, but rejoined the Congress last year in September. The announcement was made by AICC general secretary Dr. KC Venugopal.
