Naomi Osaka expresses ‘shock’ over missing Chinese tennis star Peng Shuai

Japan's world No 1 joins other athletes in voicing concern for Peng, who has not been seen since accusing ex-vice-premier of sexual assault

World No 1 tennis star Naomi Osaka has joined the growing calls for answers on the whereabouts of Chinese player Peng Shuai, who has not been heard from publicly since she accused the country's former vice premier of sexually assaulting her.

Peng, one of China's biggest sporting stars, made the claims in a Weibo post on 2 November, in which she alleged Zhang Gaoli coerced her into sex and that they had an intermittent affair.
