Sir, During the past fortnight I have sat in front of two Commons committees to explain why I believe a new Groceries Code Adjudicator would help put an end to unfair supply chain practices among the big supermarkets.

It is three years since the Competition Commission recommended the establishment of an ombudsman and it is now over a year since the Groceries Supply Code of Practice (GSCOP) came into force. We need an Adjudicator to ensure fair play via GSCOP.

Last week the Efra Select Committee recommended that the Adjudicator be given broader powers than those found in the draft Bill, such as allowing third parties like the NFU to make complaints on behalf of their members. We welcome the Committee's stance and urge DBIS to take its views on board in preparing the final Bill. Giving the Adjudicator the power to launch investigations on the basis of credible evidence, including from third parties, will send a strong message to retailers that unethical business practices will not be tolerated.
