THE Competition and Markets Authority's initial investigation into supermarket giant Morrisons’ purchase of collapsed convenience store chain McColl’s has found concerns in 35 areas where the two brands compete.

However, overall, the deal would not harm the vast majority of shoppers or other businesses, the watchdog said. The CMA launched its investigation after the companies submitted the reported £190 million deal for review.

Glasgow-founded McColl's operates cover 1,100 convenience newsagent shops, with stores across Scotland, England and Wales, while Morrisons, owned by parent company Clayton, Dubilier & Rice, has around 500 grocery stores in the UK.

CD&R is also the parent company of the Motor Fuel Group, which owns over 800 convenience stores, the vast majority of which are attached to its petrol stations.

The CMA has found in its Phase One investigation that the merger between Morrisons and McColl’s raises competition concerns in 35 areas, where McColl’s or MFG convenience stores will face reduced competition if the deal is allowed to go ahead as planned.

Weaker competition could lead to higher prices or a lower quality service for the customers in these areas who rely on their local shops for groceries, the CMA said.

During the investigation, the retailers accepted that the merger would raise concerns in some areas and asked the CMA to move straight to a discussion of remedies to address these concerns.

Morrisons now has five working days to offer proposals to the CMA to address the competition concerns identified. The CMA would then have a further five working days to consider whether to accept these in principle instead of referring the case to a Phase Two investigation.

Sorcha O’Carroll, CMA senior director of mergers, said: “As the cost of living soars, it’s particularly important that shops are facing proper competition so that customers get the best prices possible when picking up essentials or doing the weekly shop.

“While the vast majority of shoppers and other businesses won’t lose out, we’re concerned that the deal could lead to higher prices for people in some areas. If Morrisons and McColl’s can address these concerns, then we won’t need to move on to an in-depth investigation.

“In the meantime, we’re working closely with Morrisons to ensure that it can provide the support that McColl’s needs to continue to operate during our investigation.”

The convenience chain's administration came after a two-year financial struggle. Largely trading in Scotland as RS McColl, it was co-founded by Robert Smyth McColl, a Rangers and Scotland player, and his brother Tom in 1901, and the group was set up in 1973.
