A Chinese court has jailed the wife and a son of a former senior politician sentenced to life in prison a year ago for corruption amid an ongoing anti-graft campaign.

The court in the central city of Yichang said Wednesday that Jia Xiaoye, the wife of imprisoned former security chief Zhou Yongkang, will serve nine years for taking bribes.

State broadcaster CCTV said the same court sentenced Zhou's son, Zhou Bin, to 18 years in prison for taking 98 million yuan ($15 million) in bribes and running an illegal business trading in restricted commodities.

The reports said both Jia and Zhou told the court they would not appeal the verdicts.

Zhou Yongkang retired in 2012 but came under investigation the following year and was convicted in a closed-door trial.
