At least half of London boroughs are using Chinese surveillance systems made by firms linked to the abuse of Uighurs, data has revealed. Freedom of information requests filed late last year with all 32 councils in the capital, as well as 20 other major UK cities, found about two-thirds owned technology made by two Chinese companies accused of links to the repression of the minority group. The Beijing government has been accused of widespread abuse in the Xinjiang province, home to the Muslim Uighurs, including allegations of forced sterilisation, slave labour and mass internment. Members of the Uighur minority group have reportedly been made to pick cotton, leading to concerns British consumers could inadvertently be buying tainted goods.
