The question of Tibet's future has taken on urgency with the Dalai Lama turning 90 this week. Hundreds of followers have been gathering in the Indian town of Dharamshala to honour him. He announced the much-anticipated succession plan on Wednesday, reaffirming what he has said before: the next Dalai Lama would be chosen after his death.

The Dalai Lama, the spiritual head of Tibetan Buddhism, has often called himself a simple monk, but for more than 60 years armed with little more than charm and conviction, he has managed to keep the cause of his people in the international spotlight.
