   • 2017 January 14, “Thailand's new king rejects the army's proposed constitution”, in The Economist‎:

     King Vajiralongkorn has stacked his privy council with generals plucked straight from the junta's cabinet; the junta has looked to the palace to help adjudicate in a long-running and volatile dispute over who should fill a vacant post at the head of Thai Buddhism, which the military government had appeared ill-equipped to handle alone.
