JD Rymbai on Saturday quit as Meghalaya chief minister at the directive of the central leadership of Congress after a brief tenure of eight months, and veteran leader DD Lapang was sworn in to replace him.
Lapang returned to the post he had quit last year in the wake of dissidence among party MLAs.
Rymbai had on Friday refused to act on the Congress leadership's directive but changed his mind on Saturday morning after a meeting with senior leader and Union Minister PR Dasmunsi.
Ten ministers, including seven from the Congress, were sworn in as part of the new Congress-led Meghalaya Democratic Alliance coalition government.
Governor MM Jacob administered the oaths of office and secrecy to Lapang and his ministers at a simple ceremony in Raj Bhavan.
The three other ministers belong to regional allies -- United Democratic Party, Khun Hynniewtrep National Awakening Movement and Meghalaya Democratic Party. Lapang said another MLA was to take oath but he was out of station.
Lapang, who was elected the new leader of the Congress Legislature Party earlier in the day, staked claim for the post when he called on Jacob shortly after Rymbai put in his papers and went into a huddle with his supporters. Dasmunshi said the change of guard was effected democratically.
Congress President Sonia Gandhi had on March six asked Rymbai to step down.
