Cameron pledged his support last week at Prime Minister's Questions in response to Shrewsbury and Atcham MP Daniel Kawczynski (Conservative).
Kawczynski asked: "Will the prime minister have urgent talks with the leader of the house and the business secretary on introducing legislation for a national regulator or ombudsman for supermarkets before more suppliers are decimated by their conduct?"
Cameron replied: "We have new arrangements in terms of ensuring that supermarkets treat farmers fairly. All of us as constituency MPs have heard stories about supermarkets behaving very aggressively towards farmers and it is right that there is a proper way of trying to police that independently, so that our farmers get a fair deal for the food that they produce."
The Government announced in August that it will introduce an independent groceries code adjudicator. With the end of the year fast approaching, the NFU said it was working hard to make sure that the Department for Business, Innovation & Skills does not delay further in setting up this vital body. An NFU representative said: "We are glad to see the prime minister recognises how important it is."
