Tania Branigan “China indicts Bo Xilai for corruption” http://www.guardian.co.uk/world/2013/jul/25/china-indicts-bo-xilai-corruption
An editorial published by the official China News Service said Bo's indictment sent the message that "no matter who you are, no matter how high your ranking, you will be seriously investigated and severely punished if you violate party discipline and state law".
But Joseph Cheng, professor of political science at the City University of Hong Kong, said cases such as Bo's seemed to have more to do with political manoeuvres and their outcomes appeared to have been agreed before charges were laid.
"If you look at these trials, the defendants all admit their guilt quietly; they don't claim to offer important revelations about other networks and supporters; and they get very lenient sentences," he said.
"You try to avoid cases having an adverse impact on factional balances and solidarity. You never see leaders who are defiant and suddenly jump up in court saying 'Aha – so-and-so was also involved'."
