BEIJING — The Chinese authorities have sentenced Ling Jihua, the top aide of a former president and Communist Party chief, to life in prison for corruption, according to the state news media.

Mr. Ling was found guilty on Monday of taking bribes, abuse of power and illegally obtaining state secrets, the news reports said. He is one of the highest-ranking Chinese officials to be jailed for corruption.

Mr. Ling joins two other notable senior party officials, Bo Xilai and Zhou Yongkang, in receiving a lifetime prison sentence for corruption. All three men have been accused of trying to undermine the authority of President Xi Jinping, who took office in late 2012, the same year that scandals involving the three men unfolded.

Mr. Bo and Mr. Zhou are considered political enemies of Mr. Xi, and Mr. Ling is a critical player in an informal party group, known as the Youth League faction, that was a center of power before Mr. Xi became China’s top leader. Hu Jintao, the former president and party chief for whom Mr. Ling served, was a leader of that faction.
