The health of jailed Burmese opposition leader Aung San Suu Kyi is a cause for "grave concern", her National League for Democracy (NLD) party has said.
The NLD says the 63-year-old has not been able to sleep at night because of continuing cramps in her legs and needs urgent medical attention.
Ms Suu Kyi is on trial for allegedly violating the terms of her house arrest after a US man broke into her home.
She denies the charges and faces five years in prison if found guilty.
Ms Suu Kyi has suffered from ill-health in the past. Shortly before her arrest on 14 May she was treated for dehydration and low blood pressure.
The NLD said she was "in desperate need of proper medical treatment".
"We are very much concerned about her health," it said in a statement.
