Myanmar's ousted civilian leader Aung San Suu Kyi is to appear in court on Monday.

The Yangon court hearing for Suu Kyi -- who spent more than 15 years in house arrest under previous military rule -- is expected to start by video link around 10 am (0330 GMT), her lawyer Khin Maung Zaw told AFP.

The Nobel laureate faces at least four charges: possessing unlicensed walkie-talkies, violating coronavirus restrictions, breaching telecommunications laws and intent to cause public unrest.

Military authorities have also accused her of accepting illegal payments of $600,000 in cash as well as a large quantity of gold -- allegations her lawyer says are "groundless".

Khin Maung Zaw has complained he has not been allowed to meet Suu Kyi, who has been in custody since the coup, though he said the 75-year-old appeared in good health at her last court appearance, by video link, on March 1.
