OSAKA -- The son of Burma's first prime minister testified Wednesday in Osaka District Court on behalf of a male relative fighting for political asylum in Japan, saying if the government forces him to return to the country now called Myanmar he will be executed.

U Aung, the son of U Nu, postwar Burma's first leader, who was overthrown in a military-backed coup 1962, told the court his relative, Aye Kyaw Soe, who is seeking political refugee status in Japan, would be put death if he returns to Myanmar.

Soe is is related to Nu and Soe's father had also opposed the military junta led by Ne Win, which ruled Burma from 1962 until 1988, Aung said. Successive juntas have ruled what later became Myanmar since then.
