A court in military-ruled Myanmar sentenced deposed leader Aung San Suu Kyi to five years in prison on Wednesday after finding her guilty in the first of 11 corruption cases against her, according to a source with knowledge of proceedings.

The Nobel laureate and figurehead of Myanmar's opposition to military rule is charged with at least 18 offenses carrying combined maximum jail terms of nearly 190 years, all but killing off any chance of a political comeback.

The judge in the capital, Naypyitaw, handed down the verdict within moments of the court convening, said the source, who declined to be identified because the trial is being held behind closed doors with information restricted.
