Invitation to comment: closed 25 May 2018

10 May 2018: The CMA is considering whether it is or may be the case that this transaction has resulted 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 has resulted, or may be expected to result, in a substantial lessening of competition within any market or markets in the United Kingdom for goods or services.

Initial enforcement order
