A campaign led by Mary Portas aims to prevent fast fashion giant Shein from listing its shares in London due to allegations of worker exploitation, environmental harm, and tax avoidance. Shein denies these claims and states its commitment to fair work conditions. The petition, supported by various groups, urges the UK government to halt Shein's London Stock Exchange listing until a thorough investigation on labor practices, environmental impact, and tax compliance is conducted. Concerns about unethical business practices and modern slavery have fueled opposition against Shein's potential listing, with over 33,000 signatures on the petition. Shein faces scrutiny over its suitability for the UK stock market amidst growing resistance and legal challenges to its IPO plans.
