Industry leaders have admitted they weren't expecting the Code of Practice, which came into effect this week, to bring about major improvements to trading relationships within the chain. Speaking at Food & Drink Expo on Monday, Food and Drink Federation director general Sylvia Jay said: "I can't say we were happy with the first drafts and I can't say we are 100% happy with it now." National Farmers' Union president Ben Gill said the code had been "watered down to such an extent" as to render it pretty useless, although the NFU was pressing for talks with retailers to hammer out how it would work in practice. However, Asda deputy chief operating officer Richard Baker said the code with which Asda's buyers already complied was far more stringent than the one drawn up by the OFT. "There are lots of challenges facing farming and agriculture and no one part of the chain can act in isolation," he added. "We are a powerful industry and we're easy to knock, a bit like Man United." The power of the multiples had grown, said Baker, but this has been driven by consumer demand. "Consumers have chosen to come and shop with us," he said. He added that manufacturers had come out of Asda's annual supplier conference this month "very energised". {{NEWS }}
