Yangon  - Myanmar opposition leader Aung San Suu Kyi is scheduled to testify in court Tuesday against charges that she broke her terms of detention by allowing a US national to swim to her lakeside house-cum-prison, her lawyer said Monday.

At least 30 diplomats and 25 journalists will be invited to the trial Tuesday, court sources said.

"We did not have sufficient time to discuss with Daw (Mrs) Aung San Suu Kyi the full defence," Nyan Win, part of Suu Kyi's defence team, said.

The defence will present four witnesses Tuesday, including Win Tin, veteran journalist and senior executive member of the National League for Democracy (NLD) opposition party, that Suu Kyi leads.

Suu Kyi, her two house helpers and US citizen John William Yettaw, 53, have been accused of violating Suu Kyi's terms of household arrest after Yettaw entered her Yangon compound on May 3 and stayed until swimming away on May 6.

Yettaw, a member of the Church of Jesus Christ of Latter-Day Saints, faces several charges including immigration violations for visiting a prisoner while on a tourist visa, and breaking municipal laws for swimming illegally in Inya Lake, according to state media reports.

Prosecutors claimed last week that Yettaw first visited Suu Kyi's house on November 30 when he handed over his church's Book of Mormon to her servants for Suu Kyi to read.

His uninvited May 3 visit to Suu Kyi's residence has allowed the ruling junta to charge her with violating the terms of her house detention, which has lasted the past six years and was due to expire on May 27.

The new case against Suu Kyi, which began a week ago in Yangon's Insein Prison, has outraged the international community and even prompted warnings from Myanmar's close allies in the Association of South-East Asian Nations.

It is widely believed that the judges would find Suu Kyi guilty and sentence her to another three to five years in detention, long enough to keep her out of the political picture while the junta stages a general election next year.

Suu Kyi, 63, is the leader of the NLD opposition party which won the 1990 general election by a landslide, but has been blocked from power by Myanmar's junta for the past 19 years. She has spent 13 of those years under house arrest.(dpa)
