Single Payment Scheme

I congratulate my hon. Friend on securing this important debate. He has touched on food security, and I agree entirely with him on that. He has said that farming is going through a rosy patch at the moment, and that is certainly so in arable farming, but not in livestock farming. Does he believe that, despite the need for subsidies, certainly in the short term, supermarkets will play a key role in driving up incomes for farmers and how they are dealt with in future?
