The Discussion Paper examines the state of post-EU UK food security and policy. It applies a multi-criteria approach, seeing food not as a matter that can be reduced to one overarching goal – cheapness, say, or supermarket availability – but as an issue on which public policy has to weigh up and include several equally worthy and evidence-based concerns. The report offers an approach to ensuring UK food security in the years ahead. It offers nine public-interest Principles which should guide future food policy. These propose that it is possible to capture a consensus on the need for change and what it entails. Each Principle leads to a Test that the UK public and policy-makers could apply to any policy proposals for the food system that emanate from Government in coming months.
