Ms Christine Tacon:

When I visit retailers, I tell them that my day is theirs and that they can talk to me about they want. One retailer talked to me about who it was working with on beef, how it had been working with the same supplier for 20 years and had invested in that supplier. The retailer also said that it might as well sellotape money onto every single steak it sold. It was selling each one at a loss because it was paying the supply chain the right price. It had chosen to sell the beef at a loss. That retailer was making sure that the chain got paid the right price.
