Prime Minister Lobsang Sangay is running for re-election and his opponent is parliament speaker Penpa Tsering. Both continue to support "a middle way" proposed by the Dalai Lama, which calls for-seeking regional autonomy under Chinese rule.
Some groups have been advocating full independence for Tibet as little progress has been made in the dialogue with China.
On Sunday, some 80,000 registered Tibetans in exile — 11,000 of them in Dharmsala in India — are voting in a daylong election.
The result is expected next month.
