Congress on Monday appointed Lok Sabha MP Gaurav Gogoi as the new president of its Assam unit, replacing Bhupen Kumar Borah. Assam CM Himanta Biswa Sarma has constantly criticised Gogoi, accusing him of having links with Pakistan. Congress also appointed three new working presidents - Jakir Hussain Sikdar, Roselina Tirkey and Pradip Sarkar - to its Assam unit.
