A senior party leader said on condition of anonymity that Congress legislators were interviewed individually by top leaders, including Handique, Narayansamy, Wasnik and Khursheed.
Earlier in the day indication of the installation of a new chief minister came from Home Minister P Chidambaram who told reporters in Delhi that the state Governor had been asked to take "necessary consequential steps".
The swearing in of Gamlin, a leader of powerful All Arunachal Pradesh Students Union in early 1980s, came several hours after the body of Khandu, who died in the copter crash along with four others in Tawang district, arrived in Itanagar.
