There is no name or signature in direct relation to the Modern Slavery Act. However under the same tab 'Home, Our Company, Corporate Governance' there is a document 'Board Composition and Disclosure' where you can find individuals with title names. So you could assume that they agree and support the Modern Slavery Act as they are displaying their names in close proximity of the document. But it can be argued that as they are not signing the Act directly they are displaying a lack of commitment towards their statement.
