ffinlo Costain talks to Sir Dieter Helm CBE.  Dieter is Professor of Economic Policy at the University of Oxford and Fellow in Economics at New College, Oxford. He was the Independent Chair of the UK's Natural Capital Committee, and was awarded a knighthood for services to the environment, energy and utilities policy.

This discussion is a masterclass for people aiming to influence UK Government policy on agriculture and the environment. Helm is hugely engaging as he sets out his influential thinking and establishes sound criteria for support and opposition.
