Competition Commission (CC) will publish its hotly anticipated remedies report for its inquiry into the £120 billion grocery sector this afternoon after 4.30pm.

A CC spokesman said: “We are obliged to publish outside LSE trading hours and, because of the need to allow sufficient response times for the parties, we want to publish this week if at all possible.”

CC chairman Peter Freeman is considering tightening up the Supermarkets Code of Practice and appointing an ombudsman to make it easier for suppliers to resolve their grievances with supermarkets. It could also bind grocers beyond the big four to the code.

The Commission will deliver a number of remedies intended to improve competition in areas where a chain has a high concentration of stores, such as a fascia test. In addition, it is considering outlawing the practice of developers granting exclusivity to one supermarket on major brownfield development schemes.
