Midcounties Co-operative Society’s acquisition of Top 50 indie Harry Tuffins earlier this year would create competition concerns in four local areas, the Office of Fair Trading has ruled.

The society, which bought the 10-store chain in April, has offered to sell the four stores affected, which include two petrol stations.

The OFT is considering the offer. “We are concerned that customers could face an increase in prices and a reduction in choice,” it said.
