A prominent Chinese politician widely seen as a leading reformer has left his post as Communist Party secretary for a major southern province.

The official Xinhua News Agency said Tuesday that Wang Yang had been replaced as party secretary of Guangdong, which rivals Shanghai as China's most prosperous region. Xinhua gave no indication what Wang's next post might be.

Wang, 57, is seen as a politically liberal figure. He failed to win a seat on the party's ruling seven-member Standing Committee when new leaders were installed last month but was named to the lower-ranking Politburo.

Wang was considered a rival of disgraced politician Bo Xilai, who was removed this year as party secretary of Chongqing, a major city in the southwest. Wang was Chongqing's party secretary before Bo.
