CMA case J Sainsbury PLC / Asda Group Ltd merger inquiry: Sainsbury's / Asda

The United Kingdom Competition and Markets Authority blocked Sainsbury's's merger with Asda on 25 April 2019 (case J Sainsbury PLC / Asda Group Ltd merger inquiry).[1]

The Competition and Markets Authority blocked the merger of Sainsbury's and Asda in April 2019, finding it would raise prices and reduce quality across hundreds of local areas and at national level. The parties had offered to sell stores; the Authority concluded no realistic divestiture could resolve the harm, and prohibited the deal outright.
