Please refer also to Section 18 of the CMA’s Guidance on the CMA’s jurisdiction and procedure with regards to Mergers (CMA 2): https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1044636/CMA2_guidance.pdf   If the merger has been or is being notified in other jurisdictions, the CMA’s Merger Notice Template asks parties to indicate whether notifying parties would be willing to provide the CMA with a confidentiality waiver allowing it to exchange confidential information with the relevant competition agencies in other jurisdictions in respect of the notified merger. Contact with overseas NCAs is also given as an example of the type of information that notifying parties may provide to the CMA.
