The Competition and Markets Authority (CMA) has formally opened its investigation into the proposed Tesco-Booker merger.

The first phase of the investigation runs until 25 July 2017. During this period, the CMA will “assess whether the deal could reduce competition and choice for shoppers and other customers, such as stores currently supplied by Booker”, the authority stated.

After this first phase, the merger will either be cleared or, if the CMA identifies a potential reduction in competition, it will be referred for an in-depth investigation lasting up to 24 weeks - unless the two merging parties can offer proposals following the first phase of the investigation which convincingly address any concerns identified.

The CMA is now seeking views on the merger from all interested parties, with those interested invited to submit their views by 13 June 2017. Further details will be available on the investigation case page.
