China called for a lifetime ban on a referee who controversially awarded gold to a British competitor at the World Taekwondo Championships.
China labelled it "a scandal" and "bizarre" after their Olympic champion Zheng Shuyin was disqualified from the women's +73kg heavyweight final in Manchester. Despite the home fighter Bianca Walkden winning, boos rang out when the prizes were awarded.
Chinese officials were left outraged by what they called an injustice against Zheng, the 2016 Rio Olympic champion in the +67kg category, who was disqualified for racking up 10 fouls during the bout. The 25-year-old held a 20-10 lead when Moroccan referee Tarik Benradi disqualified her.
