The MSA states "We will be asking entities within our supply chain to tell us what they are doing to combat modern slavery" meaning they want primary dta on what suppliers are doing to tackle slavery.

They have also produced a modern slavery and human trafficking policy which prohibits slavery and human trafficking in any forms in the supply chain.

They state:

During the last financial year Corney & Barrow has taken the following action to detect and counter the risks of human trafficking and modern slavery taking place within our supply chain:

 We have developed and published a Modern Slavery and Human Trafficking policy.

 We have reviewed and rationalised our supplier database, ensuring that the information that we hold on our suppliers is up to date and verified.

 We have registered with HM Revenue & Customs under the Alcohol Wholesale Registration Scheme, which helps to ensure that the wine that we offer for sale originates from verifiable sources.

 We have put in place a comprehensive, risk-based process to undertake due diligence on our supply chain.

 We have undertaken a risk assessment on our supply chain with regard to modern slavery and human trafficking in order to identify those suppliers where these are at greatest risk of occurring. To do this we have examined the risks according to the country where our suppliers are based, such as Chile and Argentina, together with the sectors in which our business operates, such as shipping and haulage.

 We have prepared awareness information for all our members of staff to enable them to understand what modern slavery is and to know what to do should they suspect that it might be occurring.

Quite a few steps in terms of Codes of Conduct and Risk Assessment have been made to combat Modern slavery in the supply chain. Specific details of how malpractice is dealt with are not given
