Ms Suu Kyi was taken to prison in Rangoon on 14 May
The trial of Burma's democracy leader, Aung San Suu Kyi, has been delayed again, officials say.
Expected to resume on Friday, officials have now told reporters the trial is adjourned until 26 June.
Unnamed officials said the delay was to allow the defence team to call an additional witness.
Aung San Suu Kyi is charged with violating the terms of her house arrest, but the trial has attracted strong regional criticism.
The trial had been adjourned until 12 June while a higher court hears a request from her lawyers to reinstate three witnesses a lower court barred.
Ms Suu Kyi denies the charges and faces five years behind bars if found guilty.
The three witnesses are all from Ms Suu Kyi's National League for Democracy party. One defence witness has been allowed to testify.
Fourteen witnesses for the prosecution have been allowed to testify.
The trial's closing arguments were originally expected to be heard on 1 June. Then they were postponed to 5 June.
Ms Suu Kyi is widely expected to be convicted.
Already under house arrest, Ms Suu Kyi was detained last month at Rangoon's notorious Insein prison after American John W Yettaw swam to her lakeside home and stayed for two days.
Observers believe that Burma's military leaders will seize on the incident to keep her behind bars during what they say will be multi-party elections in 2010.
Ms Suu Kyi has been under house arrest and banned from seeing all but a small group of people for 13 of the past 19 years.
