Verified [GOV.UK (Competition and Markets Authority) press release, 31 March 2026](https://www.gov.uk/government/news/cma-announces-package-of-actions-on-business-software-and-cloud-services?ref=sovereigntymonitor.eu)

**What it does not test.** Does not establish that Microsoft has been found to hold strategic market status, since that determination follows the investigation opening in May 2026.

**How this item counts.** No movement: no answer to who owns, who operates, whose law governs or who made the parts changes. Weight 0\. Fee/interop pledges ease switching but don't change who owns/runs the clouds. [European Sovereignty Index](https://sovereigntymonitor.eu/sovereignty-index/)
