Phase 1

Launch of merger inquiry

8 January 2019: The CMA announced the launch of its merger inquiry by notice to the parties.

Invitation to comment: closes 22 January 2019

8 January 2019: The Competition and Markets Authority (CMA) is considering whether it is or may be the case that this transaction, if carried into effect, will result in the creation of a relevant merger situation under the merger provisions of the Enterprise Act 2002 and, if so, whether the creation of that situation may be expected to result in a substantial lessening of competition within any market or markets in the United Kingdom for goods or services.

To assist it with this assessment, the CMA invites comments on the transaction from any interested party.
