Question to the Cabinet Office:

To ask His Majesty's Government what discussions they have had with the Competition and Markets Authority on the expected timetable for the Strategic Market Status investigation into Microsoft’s business software ecosystem; and what steps they are taking to ensure that any remedies to address competition concerns are implemented without undue delay.

The CMA launched its Strategic Market Status designation investigation into Microsoft’s business software ecosystem on 14 May 2026.

This investigation must be completed within 9 months. An indicative timetable of this investigation is published on the CMA’s website. The CMA operates independently and decisions on which firms to investigate, and how these investigations are conducted rest solely with the CMA.
