Controversial former MP Sri Bintang Pamungkas, serving a jail term for defaming President Suharto, will be put on trial for attempting to undermine the state, a report said yesterday.

A Jakarta court would soon start hearing the subversion trial, the Media Indonesia newspaper reported. State prosecutors have prepared a 25-page document charging the prisoner with trying to undermine the state by setting up a new political party outside the three government-recognised ones.
