Co-operative Group's Southern Co-op Takeover Faces Investigation

By the Editorial Team · Wednesday, September 16, 2026

The Competition and Markets Authority is reviewing the Co-operative Group’s proposed acquisition of Southern Co-op due to concerns about reduced market competition. The CMA has given both parties until September 22 to address these issues or risk triggering a full investigation.

The Co-operative Group’s proposed acquisition of Southern Co-op is under scrutiny by the Competition and Markets Authority (CMA), which has raised concerns about the potential impact on market competition. The CMA has set a deadline of September 22 for both mutuals to respond to its issues. Should the parties fail to adequately address the regulator’s concerns, the CMA may initiate a comprehensive investigation.

The transaction would increase the Co-operative Group’s membership base significantly, incorporating Southern Co-op’s approximately 330,000 members into its existing seven million-strong membership. The deal aims to consolidate the presence of the two mutual societies, but the regulator’s primary focus is on ensuring that the acquisition does not unduly reduce competition in the sectors where both groups operate.

No further details have been released about the specific areas of competition the CMA is concerned about, but the authority’s intervention reflects its commitment to maintaining competitive market conditions. Both the Co-operative Group and Southern Co-op have yet to publicly comment on the regulator’s latest move.
