The grocery market is holding its breath this week amid fears that the Competition Commission may recommend the creation of an independent regulator to police relationships between suppliers and supermarkets.

The Commission’s long-awaited remedies statement, which will be published on Thursday, is the culmination of a two-year inquiry into the grocery sector.

A source close to the Commission said that a regulator to oversee the big four supermarkets was “on the agenda”. The source also said that a recommendation would be put forward to change the Supermarket Code of Practice, put in place after the last inquiry from the Commission.

Some suppliers are thought to be unhappy following the provisional findings by the Commission published last year, which unearthed little proof of any abuse of power by the retailers investigated.

The Commission could also recommend the enforcement of a “competition test”, which local authorities could use when considering planning applications for new supermarkets in their areas.
