While Gu was given a suspended death sentence, Wang was sentenced to a 15-year prison term.
According to the official media reports earlier, investigations have found that Bo seriously violated party disciplines while being the head of Dalian City, Liaoning province, and the ministry of commerce, as well the party chief of Chongqing.
Bo was accused of taking advantage of his position to seek profits for others and received huge bribes personally or through his family, it said.
He was also accused of maintaining improper sexual relationships with a number of women and found to have violated organistional and personnel disciplines and made erroneous decisions in certain promotion cases, resulting in serious consequences. It is to be seen when Bo's trial would begin and what sentence he would receive.
Analysts say that Bo's fall and his removal especially after the US consulate drama has made it easier for the moderate to isolate the hardliners and pack the party with followers of later reformist leader Deng Xiaoping, who succeeded Mao.
Former high profile railway minister Liu Zhijun, 59 was also accused of corruption, keeping mistresses, and perpetrating political and moral wrongdoings. He was the longest railway minister supervising most China's high-speed train network construction.
Liu was appointed vice minister of railways in 1996 and minister in 2003.
He was removed from his post and came under investigation in February 2011.
