The son of a Vietnamese revolutionary leader has been jailed for seven years for spreading anti-government propaganda through writings, internet material and foreign media interviews.
After a trial lasting about half a day, Cu Huy Ha Vu, a human rights campaigner and a legal scholar, was convicted of advocating an end to one-party communist rule.
Cu Huy Ha Vu is best known outside Vietnam for having twice tried to sue the Prime Minister Nguyen Tan Dung.
The first challenge in 2009 stemmed from a protest against a bauxite mining project and was quickly dismissed.
He sued the Prime Minister again last year for banning group legal action.
Nguyen Huu Chinh, who chaired the trial, said Vu’s behaviour was serious and harmful to society.
He said Vu’s writings and interviews blackened the Communist Party of Vietnam, both directly and indirectly.
