The Tibetan spiritual leader Dalai Lama said Thursday that he will give up his political role in Tibet's government-in-exile, shifting that power to an elected representative. The Tibetan spiritual leader, speaking on the anniversary of the 1959 Tibetan uprising against Chinese control, said the time has come "to devolve my formal authority to the elected leader." He has long insisted that he wants the exile government, based in this Indian hill town, to have more power. But the Thursday speech gave a formal time frame to that transition, saying he would propose amendments to the exile constitution during the exile parliament's next session, which begins later this month. Just how much change will come, though, is highly unclear. The Dalai Lama's political role is largely ceremonialan elected prime minister is the formal leader of the exile governmentbut the Dalai Lama's status overshadows everyone else in the movement.The 76-year-old Dalai Lama, who fled Tibet amid the failed uprising, remains deeply revered by most Tibetans despite Beijing's decades-long campaign to undermine his influence.
