“It is this ongoing consolidation of the market into the hands of just four companies that reduces the opportunity for businesses to enter and grow in the market.
“The lack of choice and diversity that this presents now and in the future is a major blow to consumer interests.”
Lowman added: “The competition authorities should not allow the sale of Somerfield to an existing Big Four retailer as this will further entrench their dominance of the market.
“Nor should the authorities allow a fire sale whereby hundreds of shops are sold to the existing dominant retailers. The end result of either is reduced choice for consumers.”
