Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, what steps is the Government taking to review public sector cloud services procurement practices in light of the Competition and Markets Authority's finding that Microsoft and AWS hold approximately 70% market share between them; and will the Government publish guidance on competitive tendering to ensure value for money.

Further to the Competition and Markets Authority findings, the Crown Commercial Service, the Department for Science, Innovation and Technology and the Cabinet Office are exploring measures to strengthen value for money and promote supplier diversification.

Procurement guidance is kept under regular review, and we will consider issuing further guidance as needed to support value for money.
