I was having lunch when I got a call from Kewal Singh, the foreign secretary, asking me to report to him immediately. It was April 7, 1973. I rushed to the foreign office. Kewal Singh, welcoming me warmly, said, ‘You are being sent to take over charge of the Sikkim government immediately. The Sikkim administration has collapsed and the Chogyal (ruler) wants immediate assistance. The people are on the streets, demanding a democratic system.
