I will inevitably return to that point a little later, as it was raised by so many Members. Let me first, however, cover the other specific points mentioned in the debate.
The hon. Member for Carmarthen West and South Pembrokeshire (Simon Hart) asked about companies outside the big 10. He is absolutely right that they are not specifically included in the Bill as levy payers, but let us recognise that the big 10 represents 95% of the grocery trade. If we are successful in the application of the adjudicator in improving standards of contract compliance, that will feed through to the rest of the sector by competition alone, if nothing else. The hon. Gentleman also mentioned length of contracts. That is not specific to the code of conduct, but the matter can be properly investigated in the context of an abusive relationship. Where such a relationship exists, that will be laid bare by the process.
The hon. Member for Bristol East made some good points about food waste. She knows that we have engaged with her on that issue and will continue to do so. I think I have a meeting with her in the near future to talk about that.
A number of Members spoke with a great deal of experience of the sector from having worked on the producer side. The hon. Members for Camborne and Redruth (George Eustice), for York Outer (Julian Sturdy) and for Sherwood (Mr Spencer), my hon. Friend the Member for Brecon and Radnorshire (Roger Williams), and the hon. Member for Tiverton and Honiton all have direct experience of working in agriculture and could tell us about the sort of downward pressures that they know suppliers regularly experience. The hon. Member for South Down (Ms Ritchie) spoke about trade associations. I hope I have been able to put her mind at rest about that.
My hon. Friend the Member for Ceredigion (Mr Williams) raised a number of important points. He spoke about access to the code and, as I said, I hope I have given him some reassurance on that. He talked about changes to the code. That is an important point. According to the process set out in the Bill, the adjudicator can put forward for consideration changes to the code, but that proposal goes back to the Competition Commission for consideration before being put before the House. It is important that we maintain that linkage because fundamental to the Bill is the abuse that the Competition Commission identified between major retailers and their suppliers. It would be a great mistake for the House to substitute our opinion for the evidence adduced by the Competition Commission.
My hon. Friend also mentioned retrospectivity. Let me underline the point again. If an abuse is continuing at the time that the adjudicator is appointed, it is proper that he or she should investigate that abuse, but we have a strong principle in British legislation that we do not apply retrospectivity to something that occurred before the date that a particular statute comes into effect. Therefore it would not be entirely proper for the adjudicator to look at complaints within the terms of the code that pre-dated that appointment if they no longer continue.
