What happened

Vodafone and CK Hutchison announced on June 14, 2023 binding agreements to merge Vodafone UK and Three UK, with Vodafone owning 51% and CK Hutchison 49% of the roughly £15 billion combination — creating Britain's largest mobile operator with about 27 million customers. After a fourteen-month review, the Competition and Markets Authority approved the deal in December 2024 with behavioral commitments rather than divestitures: an £11 billion joint network investment plan, three-year caps on selected retail tariffs, and pre-agreed wholesale contract terms protecting MVNOs on the combined network. The merger completed on May 31, 2025 as VodafoneThree.

Why it matters

The CMA just reversed a decade of European four-carrier orthodoxy, and it did so by accepting an investment promise instead of demanding a structural fix, a gamble that a bigger, better-funded network serves competition better than a fourth struggling operator. The MVNO provisions are the tell for where regulatory thinking has landed: wholesale access is now treated as the competition backstop, meaning virtual operators are no longer an afterthought in merger math but the mechanism that makes consolidation tolerable. Every operator pair in Europe eyeing a merger will cite this precedent by name. The catch is that behavioral remedies are only as strong as their monitoring, and the CMA has volunteered for a decade of homework it has historically preferred to avoid.
