A court in military-ruled Burma will deliver its verdict in the trial of Aung San Suu Kyi on Friday, her lawyer says.

The charges could see the democracy leader jailed for up to five years.

Burma's junta has sparked international outrage for prosecuting the Nobel peace laureate for breaching the rules of her house arrest after an American man swam uninvited to her lakeside house in May.

"The verdict will be given this coming Friday. We are hoping for the best but preparing for the worst," defence lawyer Nyan Win said after the trial wrapped up with a final reply by Suu Kyi's legal team.

Judges Thaung Nyunt and Nyi Nyi Soe indicated to the court at the notorious Insein prison, where Suu Kyi is being held, that sentencing was expected on the same day, Nyan Win said.

"We have a good chance according to the law, but we cannot know what the court will decide because this is a political case," said Nyan Win, who is also the spokesman for her National League for Democracy.

"If she is released unconditionally she will be home on that day - if not, the sentence will be together with the verdict."

The verdict is widely expected to be guilty, given the previous form of Burma's courts, which have handed down heavy sentences to dozens of dissidents over the past year.

But the Suu Kyi case has been repeatedly delayed since it started on May 18 amid signs that the regime is trying to quell the storm of international outrage over its treatment of the opposition leader.

U2 singer Bono publicly announced during a concert in Dublin on Monday that Suu Kyi had been named Amnesty International's ambassador of conscience for 2009, the rights group's highest honour.

Diplomats from Thailand, Japan, Singapore and the United States attended Tuesday's hearing, a Myanmar official said on condition of anonymity. Most of the trial has taken place behind closed doors.

Critics have accused the junta of trying to keep Suu Kyi locked up ahead of elections next year, and US Secretary of State Hillary Clinton led calls for her release at an Asian security conference last week.

Suu Kyi has been in jail or under house arrest for 13 of the last 19 years since the junta refused to recognise the NLD's landslide victory in Burma's last national elections, in 1990.
