CMA blocks merger between Sainsbury鈥檚 and Asda
The CMA has blocked the Sainsbury鈥檚 / Asda merger after finding it would lead to increased prices in stores, online and at many petrol stations across the UK.

In its final report, published today, the Competition and Markets Authority (CMA) found that UK shoppers and motorists would be worse off if Sainsbury鈥檚 and Asda 鈥� two of the country鈥檚 largest supermarkets 鈥� were to merge. This is due to expected price rises, reductions in the quality and range of products available, or a poorer overall shopping experience.
Following an in-depth investigation, a group of independent CMA panel members concluded that the deal would result in a substantial lessening of competition at both a national and local level for people shopping in supermarkets. This would mean shoppers right across the UK would be affected, not just in the areas where Sainsbury鈥檚 and Asda stores overlap.
Stuart McIntosh, chair of the inquiry group, said:
It鈥檚 our responsibility to protect the millions of people who shop at Sainsbury鈥檚 and Asda every week. Following our in-depth investigation, we have found this deal would lead to increased prices, reduced quality and choice of products, or a poorer shopping experience for all of their UK shoppers.
We have concluded that there is no effective way of addressing our concerns, other than to block the merger.
The CMA鈥檚 investigation found that, as well as affecting in-store customers, the merger would result in increased prices and reduced quality of service, such as fewer delivery options, when shopping online. Furthermore, it would lead to motorists paying more at over 125 locations where Sainsbury鈥檚 and Asda petrol stations are located close together.
In making the decision to prohibit the merger, the Group reviewed a wide range of issues in detail, such as the increased competition presented by discount stores like Lidl and Aldi, and how new or expanding competitors could affect the retail market, including online. Whilst the panel carefully considered these industry developments, they did not allay its serious competition concerns about the merger.
The Group also carefully reviewed the companies鈥� statement they would cut some prices. However, detailed analysis of the impact of the deal clearly showed that, overall, the merger would reduce competition in the market and is more likely to lead to price rises than price cuts.
This final decision to block the deal follows the publication of the CMA鈥檚 provisional findings and a subsequent consultation period, during which the CMA reviewed responses from a variety of interested parties, including Sainsbury鈥檚 and Asda themselves.
