PARIS — LVMH's second-largest fashion brand Dior was until last month behind on disclosures required by UK law about working conditions in its supply chain and made outdated statements on its website of a third-party certification that it terminated more than a year ago, Reuters has found.

In Britain, the Modern Slavery Act of 2015 requires companies with UK turnover of 36 million pounds ($46 million) or above to publish annual statements on their websites detailing the steps they are taking to combat forced labor in their business and supply chains globally.
