BEIJING — A former Chinese official at the center of a sex scandal has been sentenced to 13 years in prison for taking bribes of more than 3 million yuan ($510,000).

Friday's sentence comes as China's leadership is vowing to crack down on widespread graft.

The official People's Court Daily said the punishment meted to Lei Zhengfu includes confiscation of personal assets of 300,000 yuan ($48,000). The former Communist party chief of a district in the south-central city of Chongqing did not say if he would appeal.

Lei's case has riveted the public since video clips went viral of the portly 55-year-old having sex with a woman hired by property developers allegedly in an extortion scheme. The scandal exposed how sex, power and money have become intertwined in Chinese society.
