Ousted leader Aung San Suu Kyi asked the people of Myanmar to stay "united" in the face of military rule, her lawyers said Tuesday, as she reappeared in a junta court.

The Nobel laureate, and daughter of independence hero General Aung San, has been under house arrest since a February coup that sparked huge pro-democracy protests the junta has tried to crush with deadly force.

Invisible to the outside world bar a handful of courtroom appearances, Suu Kyi, 76, has been hit with an eclectic raft of charges. She could face more than a decade in prison if convicted on all counts.

On Tuesday, she heard testimony that she flouted coronavirus restrictions during elections her National League for Democracy (NLD) party won by a landslide last year, her lawyer Min Min Soe told reporters.

"She asked the people to stay united and be consistent," she added.

The specially-convened court in the capital Naypyidaw also heard testimony on a separate charge of sedition, although Suu Kyi's legal team argued two documents submitted by the prosecution were inadmissible as they were unsigned.

Former president Win Myint and senior NLD leader Myo Aung are also on trial for sedition and appeared beside Suu Kyi on Tuesday.
