Beijing’s public security minister will take over as the country’s top security chief following a twice-a-decade leadership reshuffle of the ruling Communist Party. Guo Shengkun, also a new member of the 25-member Politburo, will succeed Meng Jianzhu as party secretary of the Political and Legal Affairs Commission of the Central Committee, state news agency Xinhua reported. Guo for the first time presided over a commission meeting on Tuesday in Beijing. It is not yet clear who will take over from Guo, but the South China Morning Post reported on Monday that Zhao Kezhi, former party boss of Hebei province, was the front runner for the role.
