 This position, sometimes referred to informally as the prime minister of the Tibetan government-in-exile, became an elected position in 2001.In 2011, shortly after the election of Lobsang Sangay and upon the resignation of the Dalai Lama as the overall leader of the CTA, the head of the Kashag became the highest political official in the Tibetan exile community.According to Michael Backman, notable past members of the Cabinet include Gyalo Thondup, the Dalai Lama's eldest brother, who served as Chairman of the Cabinet and as Minister of Security, and Jetsun Pema, the Dalai Lama's younger sister, who served variously as Minister of Health and of Education.
