Burmese opposition leader Aung San Suu Kyi has suspended her campaign because of ill-health a week before she is due to stand for a seat in parliament.
She is contesting one of 45 seats in contention in by-elections next week.
A spokesman said she was suffering from low blood pressure and had been vomiting, due to exhaustion.
She also complained of sickness during an earlier campaign tour in the north of Burma and doctors have now advised her to rest.
The elections - in which Aung Sang Suu Kyi is competing for the first time since 1990 - are being seen as a crucial test of the nominally civilian government's commitment to political reform.
