Jia, Zhou Yongkang's second wife, was also fined 1 million yuan.

Earlier reports said Jia, a former editor at China Central Television, married Zhou Yongkang "around 2001".

Neither Zhou Bin nor Jia will appeal, according to a statement issued by the court after the trial.

In July 2014, the CPC Central Committee announced that it had decided to place Zhou Yongkang under investigation. He was expelled from the Party in December that year.

On June 11 last year, he was sentenced to life imprisonment for accepting bribes, abuse of power and deliberately disclosing State secrets.

Wednesday's verdicts came six months after President Xi Jinping issued a warning of "cabals and cliques" in the Party, and reiterated the nation's determination to press ahead with the fight against corruption.

Zhou Yongkang was reported to have formed several networks in the sectors he was in charge of, including law enforcement organs and State-owned enterprises such as China National Petroleum Corp.
