Law enforcement and judicial officials in China must be absolutely loyal to the ruling Communist Party, state media said, in the latest warning about loyalty in the wake of the jailing of former domestic security chief Zhou Yongkang. Zhou once ran China’s fearsome domestic security forces, but was jailed for life in 2015 for bribery, leaking state secrets and abuse of power, the most senior Chinese official to be ensnared in a graft probe since the ruling Communist Party swept to power in 1949.
